Name to Structure (n2s)
CAS Registry Numbers® can be converted to structures even when they contain coordinate bonds¹.
Conversion of nitrogen-substituted acetohydrazides is now supported.
Elements with isotopes, such as (14)C, are converted in name to structure by default, and, optionally, they can be converted with document to structure using the "d2s:elements" format option.
Some OCR errors have been fixed in carbon ranges for homology groups, for example, "Ci_10 alkyl".
Generic structure names (such as "alkyl" in English) are supported in Chinese as well, for instance, N-???-4-??? and C1-C4-??.
Polyspiro names with a polycyclic component, such as dispiro[cyclohexane-1,2'-indene-1',2"-imidazole], are supported.
Document to Structure (d2s)
For enzymes with a substrate in their name, such as "serine protease", the substrate (serine) is not converted by default. A new format option, "d2s:substrates", enables the recognition of the substrate in such cases.
New format option "d2s:specific" has been added to convert only specific structures. This option excludes structures with R-groups from the conversion.
More OCR error correction is performed.
In the case of processing XML fragments not starting with "<?xml version="..."?>", it has become possible to specify that the input text is in XML format by using the "d2s:content-type=application/xml" format option.
Metadata is also extracted from older (since 2001) USPTO patents in XML format: the section where a name is found is recorded as metadata (title, abstract, description, or claim number). Furthermore, document metadata is extracted as well: patent title and ID, inventors, IPC categories.
OCR error correction has been added for Chinese names.
Structure to Name (s2n)
In fused ring systems with an atom being in a non-standard valence state, the generated name conforms to the IUPAC rules by using the lambda notation only in front of the fused names and not inside the component name.
See for instance: 1H,3H-2λ4-naphtho[2,3-c]thiophen-2-one.
Name generation has become faster by about 10%.

Erasing a structure without an R-group attachment left "1" on the canvas, which behaved as an atom.
When an atom was selected and the "R-group attachment" button of the Markush toolbar was used, the selected atom was changed to an R-group attachment point; however, a new R-group attachment should have been added to the selected atom in this case.
Dragging with the R-group attachment tool, a bond was created connecting two R-group attachments.
Using the R-group attachment tool, R-group attachments could be added to an existing R-group attachment.

Names could not be generated for structures with lone pairs (MolAtom.LP).
The name generated for OH- was "oxidanide" instead of the preferred form "hydroxide".
An extra locant was included in the name of cyclic structures with multiple hetero atoms with one of them having non-standard valence, for instance, 1λ6,4-thiomorpholine-1,1-dione instead of 1λ6-thiomorpholine-1,1-dione.
In cases where a cyclic substituent was connected indirectly to the parent through an ether, sometimes wrong names were generated.
Name generation failed for structures with a methanethione parent.

Name to Structure (n2s)
Name and corporate ID resolution webservice now supports NTLM authentication.
Names with a missing dash before the suffix locants are now recognized.
Non-standard IUPAC specification of stereochemistry inside suffix locants is supported.
Names with superscript locants of a bridged ring system numbering are denoted by spaces are now supported.
As a result of numerous improvements to the systematic name conversion algorithm, more names are converted by n2s and detected by d2s. The accuracy of structure generation has also increased. (For instance, 5% more names were detected and converted in a large, diverse set of patents.)
An example custom dictionary has been added to the documentation.
Document to Structure (d2s)
Chinese names are now detected in text documents using an approach which recognizes names in Chinese sentences without the spaces that separate words in English.
In addition to OSRA, the CLiDE and Imago Optical Structure Recognition tools (Chemical OCR) can be used to convert images to structures. These tools need to be installed separately from Marvin.
When processing USPTO patents in XML format, the section in which a name is found is recorded as metadata (title, abstract, citation, description, or claim number). Additionally, document metadata is extracted (patent title and ID, inventors and assignees, IPCR categories).
When processing a USPTO patent XML document, referenced CDX files are imported automatically if they are in the same directory as the XML file.
Processing of USPTO XML patents has become faster: an average 20% speed-up, more than ten times faster process for some patents.
PDF document pages with images in the JBIG2 format are now supported.
PDF documents generated by Adobe Acrobat Paper Capture Plug-In and ExperVision are now handled specially, since they contain both an original scanned image of text and the text resulting from OCR of the image. This allows much faster processing of such documents, and avoids double hits for the same text.
PDF documents with many small high-resolution images are now processed much faster, even when Optical Structure Recognition is used.
The document creation date property is stored as a java.util.Date object instead of string.
Structures returned by image recognition tools (OSRA, CLiDE, Imago) are better filtered to avoid false positives.
OCR processing for scanned texts can be disabled using the -ocr format option.
Processing of PDF documents with scanned black and white images ( e.g. , most non-searchable patent documents) has become approximately two times faster.

Name to structure (n2s)
Names with a cis- or trans- imine bond were failing to be converted to structures
Ions, such as "bismuth(3+)", were imported with valence property set to 0.
Ortho substitution on acetophenone generated wrong structures.
Some E/Z and R/S stereochemistry was missing in structures imported from names when the locant of the atom or bond with stereochemistry was not specified explicitly.
The "H-" ion was missing from names containing "hydride", e.g. , sodium hydride, they only had e.g. , "Na+ instead of the correct NaH.
Names containing atoms with both a non-standard valence (λ) and a positive charge were converted to structures with an extra implicit hydrogen on that atom.
Primary and secondary amine oxides were represented as N-OH instead of [N+]-[O-].
The "Name" format was not automatically recognized for names with XML/HTML character references, such as "β" or "α".
In some cases, amino acids with α, β, and γ prefixes were not converted.
Using n2s in the applet required the downloading of an unnecessary component. This, in turn, made the first applet usage much slower.
Document to structure (d2s)
Some common words such as "DUST" or "crank", were recognized as names because, e.g. , DUST is a rare acronym for a chemical structure. These words are now ignored.
The insideTag format option was not working for XML and XHTML documents.
Some uppercase words were mistakenly recognized as SMILES strings, such as "CISCO" or "ON-OFF".
Some embedded images were returned with 'PNG' type instead of 'OSR', and the usual OSRA options and properties ( e.g. , timeout, confidence filtering) were missing as well.
When d2s was interrupted (for instance, by a timeout), an OCR or OSR process could be left running in the background until it was completed. In similar cases such processes are now stopped immediately.
Extracted names sometimes contained some irrelevant characters at the end, such as "4-(trifluoromethyl)-2-((1H-1,2,4-triazol-1-yl)phenyl)-methanamine 2e" instead of "4-(trifluoromethyl)-2-((1H-1,2,4-triazol-1-yl)phenyl)-methanamine".
In some cases, single names separated by space were imported as if they were one compound, for instance, "2-hexanoyloxyethyl 1-formyloxypropyl".
Embedded structures in Office documents were always imported with the absolute chiral flag set.
Structure to name (s2n)
When generating names in parallel in multiple threads, some E/Z stereo bond modifiers were missing from the output.
Wrong names were generated for structures with multiple attachment points. These cases are now detected and no name is generated for them. Generating a name in this case will be implemented in the future.

Name to Structure (n2s)
Initial support for Chinese IUPAC and common names has been added, e.g., 2-??-4-????.
Names with extra closing brackets can be converted when OCR error correction mode is enabled.
Name to structure now also works when bridge and spiro numberings are represented by using unicode superscript numbers, such as: tetracyclo[12.4.0.02,6.07,12]octadecane.
Custom webservice to extend name to structure conversion - for instance using corporate IDs (e.g., ABC0001234) or common name dictionaries in addition to the default one - is supported.
Automatically fix and import spiro names where the superscript formatting has been lost, for instance, after copy-pasting. As an example, trispiro[2.2.2.29.26.23]pentadecane will be imported as if from the correct form, trispiro[2.2.2.29.26.23]pentadecane.
Name to structure now works on names of bridged ring compounds where the superscript formatting of ring numbering is not present.
The custom dictionary can be encoded in UTF-8 - even if the system default encoding is not UTF-8 - providing a byte order mark (BOM) for the file. This can be used, for instance, to support dictionary in multiple languages on Windows OS.
Document to Structure (d2s)
Invalid hexadecimal character entities (e.g., "lah") are now ignored instead of making the document processing fail.
Image to structure conversion using OSRA is working on Mac OS X.
Text OCR for scanned documents is now supported on Mac OS X.
Documents compressed in xml.bz2 and xml.xz formats can be processed directly.
The memory usage has been reduced when processing documents with several thousand hits. This improvement is in addition to the memory improvements already present in version 5.11.
Option "+/-groups" has been added to enable (+) or disable (-) the conversion of groups and fragments, such as "ethyl", "nitro", "phenoxy", etc.
OCR of scanned PDF documents has been improved on Windows OS thus reaching the same performance level as that of OCR on Mac OS X and Linux OSs.

Deleting "extra" explicit hydrogens from an atom with valence error resulted in the appearance of erroneous implicit hydrogens on this atom.
When there were several disconnected structures on the canvas, partial clean was very slow.
It was possible to create a molecule with R-group definition containing a single attachment point (and no other atoms or bonds).

RS - as the marker of racemates - was not converted properly, for instance in (2RS)-1-(Adamantan-1-ylamino)-3-phenoxypropan-2-ol.
Lower CamelCase chemical names (such as 2-cyclopropylPiperazine) were not converted to chemical structures.
Common names, which are also non-chemical names, were recognized as chemical names during automatic format recognition, e.g., "Royal Blue".
E/Z bonds were sometimes set to the opposite value (in cases of non-trivial CIP rules).
For some rare inputs, which are not valid names, n2s created invalid structures that could be exported to mol format but could not be opened.
Both "phenylene" and "phen-1,3-ylene" were wrongly converted to benzene. Now all forms convert to the correct structure with two attachment points, including "m-phenylene", "1,3-phenylene", and "phen-1,3-ylene" (similarly for the o-, p-, 1,2-, and 1,4- forms).

Names, such as "methyl ether", are used either to denote a group (CH3-O-*) or the dimethyl ether compound (CH3-O-CH3), as well. The default behavior still is to generate the complete compound, but a new name option "expectGroup" has been added to get the group instead.
A name converter can now prevent a name from being converted (even by other lower-priority converters). See the API of the chemaxon.naming.NameConverter class.
Document to Structure (d2s)
Peptide 3 letter abbreviations are now recognized in documents, for instance ValGlySerAla or Val-Gly-Ser-Ala.
A new option has been added to control the maximum time allowed for processing a document: format option "d2s:timeout=60" to allow a maximum of 60 seconds. Default is 0 meaning infinite timeout.
A new option has been added to disable the extraction of OLE embedded structures from Office documents (option name: "d2s:-ole").
Structures imported from the custom name dictionary now have the "Type" property set to "custom" instead of "common".
Memory usage has been significantly reduced when processing large PDF documents (for instance hundreds of scanned pages).
Structure image conversion by OSRA has become faster, resulting in more structures converted when previously a timeout was reached.
CAS Registry Numbers® (which typically include commas) are not converted by default by d2s anymore (they are still converted by n2s). The old behavior can be activated by using the "d2s:CASnames" format option.
The unwanted interpretation of some common words as chemical names, that are frequent especially in patents, has been avoided. For example, the 'amino' group when used in the phrase 'amino acid', or 'Ser' when it is not the abbreviation of Serine but 'Ser. No.' for 'serial number'.
Structure to Name(s2n)
Multiple name generation tasks can now be run in parallel at full speed to make use of multiple CPUs and cores.
Multiple name import tasks now run faster, as partial locking is no longer required and has been removed.
Generated names now use unicode characters when needed, for instance, 6λ4-thiadispiro[5.2.59.26]hexadecane instead of 6$l^{4}-thiadispiro[5.2.5^{9}.2^{6}]hexadecane. The pure ASCII output can be generated using the "name:ascii" format option.

AV (abnormal valence) property is now stored in atom property and not set as atom valence. The VMN valence representation will be revised in a later version.
Deuterium and tritium count property is handled properly in VMN (added as D and T ligands for non-homology atoms). D and T are transposed during the import in comparison to the VMN, as this represents the correct information in the majority of the MMS database.
Correcting incorrect atom types in VMNs: C0 is transformed to CHK; C1 is transformed to C; homology groups in ring are transformed to XX
Attachment bond type is set to parent R-atom bond type if different.

Improved R-group Attachment Error Checker detects R-group definitions having incorrect R-group attachment orders. Fixer is not available for this feature yet.
New Explicit Hydrogen Checker options are ready for use.
Checkers that are not recognized as internal or external checker are called: "Invalid Checkers". Invalid Checkers cannot be used in valid Structure Checker configurations; they need to be removed to perform proper working behavior.

Document to Structure (d2s)
Several names separated by a comma were sometimes wrongly recognized as a single name.
Document to structure was leaking some memory in a way that was problematic for extremely large documents (tens of thousands of structures in a single document).
When using the d2s API, waiting threads could be left behind when large documents were converted but the structures were not read until the end. This is now fixed, provided the client calls MolImporter.close().
Document to structure was not processing text from PDFs with non-standard fonts, for instance English text encoded in Japanese fonts.
Certain images in PDFs were not processed correctly by OSRA during optional image-to-structure conversion.
Names found in documents may have included unwanted trailing characters when the next word started with an open bracket, for instance, "cholesterol [28]" instead of "cholesterol".

Coordinates of graphical objects were incorrectly imported from CDX files. Currently, imported "Anonymous Alternative Groups" are placed next to the imported molecule; "Anonymous Alternative Groups" with no bonds are imported as textboxes.
MRV attributes that contain line breaks were not exported correctly: \n , \r , \r\n were not escaped.
SKC
Atom and bond colors, font types, and bond thickness in SKC import and export were incorrect.
SKC import was failing on some structures containing built-in abbreviations.

Name to Structure (n2s)
Conversion of systematic names has been increased by about 5%, and increased accuracy of the generated structures.
Prefix "nor" has been implemented (e.g., 17-Hydroxy-19-norpregn-4-ene).
Name with stereo-markers "r" or "s" where such stereoconfiguration cannot be present are now interpreted as "R" or "S". This allows names that have been completely lowercased to be converted correctly.
Document to Structure (d2s)
Document to Structure supports the following common office document formats: doc, docx, ppt, pptx, xls, xls, odt in addition to pdf, xml, html and txt.
Format options have been added to d2s, to specify what input formats should be converted (for CAS Registry Number®, SMILES and InChi). Format option "insideTag=<tag>" to restrict conversions to the content of a specific tag (for instance in HTML).
The type of source text used for the conversion is included in generated structures. Possibly values: systematic, generic, common (for names), smiles, InChI, CAS Registry Numbers® (for text formats), cdx, mrv, symyx (for embedded structures in office documents).
Processing speed has been increased: doubled on typical documents including chemical names, and tripled on documents with few chemical names.

"Marvin Services" has been introduced: Web/local services client, which provides seamless integration of third-party calculations into Marvin Sketch, cxcalc, and via Chemical Terms into Instant JChem or JChem for Excel. Industrial standard solutions like SOAP with WSDL are supported, along with the more lightweight XML-RPC or JSON-RPC protocols. Java based calculations can be called without server, directly from the jar file.
A new type of fragmentation has been implemented where the fragments contained in the same S-group are not separated. Fragmentation methods now have fragmentation type as parameter. The three types of fragmentation are:
Basic: no S-groups are considered, fragments are separated even if they are in one S-group. Broken S-groups are not added to the fragments.
Keeping multicenters: multicenter S-groups are kept in one fragment, other types of S-groups that contain more than one fragment are not added to the fragments, those fragments are separated.
Keeping S-groups: all S-groups are kept, fragments in the same S-group are not separated.
Previous fragmenting methods which did not indicate the type of fragmentation are deprecated; they do the same as before (keep multicenters), but now – correctly – without generating inconsistent molecules with broken S-groups. These methods will be removed in later releases.

MDL Molfiles: S-group parent list (M SPL in V2, PARENT in V3) and expansion information (M SDS EXP in V2, ESTATE in V3) are stored.
Incompatible API change in the MolImportIface interface: molecule import modules must implement the createMol() method.
MolConverter and MolExporter fix: created text files are in the local text format (instead of unix) if the useSysEOL boolean argument is true. The molconvert program writes OS dependent end of lines always.
S-groups
Embedded S-group support (in MDL Molfiles and Marvin Document Format).

Atom and bond set coloring can be used together with other color schemes. Atoms and bonds in set 0 are displayed in Monochrome, CPK, Shapely or Group color scheme, but other sets are displayed with atom/bond set colors if the value of the setColoringEnabled applet parameter is true (default).
Deprecation:
Use the atomSet applet parameter instead of set, atomSetColor instead of setColor and the MView.setAtomSetColor() and MarvinPane.setBondSetColor() methods instead of setSetColor.
Use colorScheme="mono" and setColoringEnabled=true settings instead of the deprecated "atomset" color scheme.
Import/export:

Base64 encoding/decoding.
Import options for input files are specified in braces instead of parentheses ("file{options}") to avoid conflicts with ugly SMILES strings ending with a branch specification. For backward compatibility, parentheses still work after filenames (but not after SMILES strings).
3D:
Document editing with graphics objects in sketcher
Calculator plugins
Support electrolite concentration is taken into account in log P and log D calculations.
Concentration of K, Na and Cl ions can be adjusted in the range of 0 - 0.25 mol/l.

Double click in Windows operating systems opens chemical files with the MarvinView application.
Deprecation: SketchMolecule (replaced by MDocument), SuperAtom.updateSgroupCrossings() (replaced by Sgroup.findCrossingBonds())
Incompatible change: chemaxon.struc.sgroup.Contractable interface removed, Expandable changed. This change was required because MDL's incomplete multiple group expansion had to be simulated for proper molfile export.
Bugfixes: in MViewPanel.setParams, in Dreiding forcefield, PDB import, atom lists in V3 molfiles, resize of MViewPanel and MSketchPanel, R-logic, etc.

Molfiles:
Sgroups are also imported as (PDB) residues. As a consequence, the PDB-specific coloring styles, "shapely" and "group", are also applicable to molfiles containing Sgroups.
Extended (V3) molfile export.
Changes in V2 format:
3D molecule coordinates are stored in Angstrom units. The unit can be specified as an import option.

Molecule.toBinFormat method to convert molecules into binary formats such as JPEG/PNG/PPM.
The type of the rendering, colorScheme, implicitH, downWedge, navmode properties in PropertyChange events is String just like the argument type of their set methods. (Previously, the two types did not match.)
Binary export formats: GZIP, JPEG, PNG, PPM
User defined export module creation by overriding chemaxon/marvin/util/MolExportModule.
Text field (T) component for MView tables.
cacheMols applet parameter for caching loaded molecules.
loadMols applet parameter for preloading molecules.
File formats
New: XYZ import
New: Extended Molfile (V3.0) import.
CML export options changed, cml:1 -> cml, cml:0 -> cml:A, cml:A writes three coordinates for each atom even if the molecule is 2D (so Jmol can read the file)
MView applet:
Animated XYZ files can be displayed
New parameters: animFPS, animDelay, animSync.
MarvinSketch Applet/Bean:
New: File/New menu item in the bean. If your application using the bean has a File/New Window menu item, then File/New should be moved to File/New/Clear current, and File/New Window should be moved to File/New/New Window. See the MarvinSketch application source (marvinbeans/examples/sketch/chemaxon/marvin/Sketch.java) for details.
"Visual fragment placement" can be disabled: use the simpView parameter or the View/Misc/Object in Hand option if you do not like to see what you are doing.
Bond length related changes.
Class library:
Changes related to atomic coordinates and transformations
New: CTransform3D class for general 3D transformations (like in Java3D)
Molecule.rot(...), tra(...), magnify(...) removed, use transform(CTransform3D T) instead
Atom coordinates became absolute
Molecule.getO() and setO() replaced by getLocation() and setLocation()
Molecule.getCenter() renamed to calcCenter(), and it calculates center of mass instead of geometrical center
New: Molecule.moveTo(location)
CGraph.indexOf changes
Splitted into two methods, indexOf(CNode atom) and indexOf(CEdge bond)
Speed improvement. CNode and CEdge has an index field that contains the object's index in its parent graph. Calling the parent graph's indexOf method returns the value of this field. The index is only searched (in the old way) when the CGraph is not the direct parent.
Valence rules
New: MolAtom.ionChargeOf(Z)
MolAtom.negoxOf(Z, boolean) removed, negOxOf(Z), posOxOf(Z) created instead
SDF properties
"name" and "informat" are no longer stored in the properties hashtable, they became fields of Molecule
Molecule.getProperties() removed
Molecule.clearForImport() -> clearForImport(name)
New methods in Molecule: getName, setName, getInputFormat, setInputFormat, getPropertyCount(), getPropertyKey(n), getPropertyKeys()
Bond length related changes.
API simplification: internal bond length of Marvin fixed to be MolBond.CCLENGTH
bondlen, rescaling applet/bean parameters, setBondlen, getBondlen, setRescaling, getRescaling methods removed, use MSketch.getMol("mol:b=XXX") instead of
The bondlen argument of Molecule.clean(dim, bondlen, opts) removed, use clean(dim, opts)
MolBond.DEFAULT_LENGTH renamed to MolBond.CCLENGTH
MolBond.getDesiredLengthRatio() removed, use the new dimension dependent Molecule.getDesiredLength(bond) method instead
MolAtom.covalentRadiusOf(Z) -> covalentRadiusOf(Z, bondOrder)
The "style" applet parameter renamed to " rendering because of a conflict with a Netscape keyword. The getStyle, setStyle methods of the beans are also renamed to getRendering, setRendering.
New rendering style: "Wireframe with Knobs".
Atoms can be highlighted in the MView/JMView applets by specifying a selection.
All query atoms and extra bond types can be enabled by omitting the queryAtoms, atomStrings, and extraBonds parameters.
"Cis or Unspecified" and "Trans or Unspecified" bond types; "ctu" in extraBonds.
Cleaning options can be specified using the cleanOpts applet parameter.
Optional down wedge bond orientation (MDL or Daylight) using the downWedge parameter.
New MView/JMView applet methods:
getAtomCount(moleculeIndex) to query the number of atoms in a molecule cell
isSelected(moleculeIndex, atomIndex) to query whether the specified atom is selected or not
selectAtom(moleculeIndex, atomIndex, select) to (un)select an atom
selectAllAtoms(moleculeIndex, select) to (un)select all atoms
Real scrolling in MView!
The applet is scrollable if visibleRows is less than rows or visibleCols is less than cols.
The names of the layout i and param i parameters changed to layout and param for the molecule cells, layoutH and paramH for the optional header.
The scroll parameter ceased to exist.
Class library:
RgMolecule for R-groups
Thread safe API for molecules
New methods in CGraph: getCtab(), getBtab(), fragments(), findFrag(), getFragIds(), getLock(), getParent(), etc.
New methods in CNode: getLigand(i), getEdge(i), getEdgeCount()
CNode.findFrag() and CGraph.fuseFrag() removed
CGraph.getEdge(i), CGraph.getNode(i), Molecule.getAtomArray() created; CGraph.getEdges(), CGraph.getNodes(), Molecule.getAtoms(), Molecule.getBonds() removed
Molecule.reuseAtom(Z, i) and Molecule.endReuse(na) created, MolAtom.reuse(Z, mol, i) removed
The two-argument MolAtom.setCharge method removed. Instead of a.setCharge(charge, false), use a.setCharge(charge); a.setFlags(0, MolAtom.FIX_CHARGE);
SMILES import
Class library:
CGraph.fuseFrag(CNode a) has only one argument.
CGraph.removeNode and removeEdge instead of remove and removeRef; removeEdge leaves edge.node1 and edge.node2 unchanged (they were set to null in removeRef).
MolBond.setFlags(int flags, int mask) method introduced.
Stereochemistry: double bonds can also be UP/DOWN (not just CIS/TRANS); CIS and TRANS information can also be stored (not just EITHER). The MolBond.getStereo and setStereo methods and the UP, DOWN, EITHER constants ceased to exists, the STEREO1_UP, STEREO1_DOWN, STEREO1_EITHER, STEREO2_CIS, STEREO2_TRANS, STEREO2_EITHER, STEREO_CARE flags introduced instead.
MolBond.getTopology/setTopology ceased to exist, the TOPOLOGY_RING, TOPOLOGY_CHAIN flags introduced instead.
Structures are colorful by default. Colorization can be disabled by setting colors=mono, both in the sketcher and the viewer.
Spacefill rendering can be enabled instead of wireframe by using the style parameter.
Atom labels can be hidden with the labels parameter.
Up/down and cis/trans either bonds
Classes in chemaxon/beans moved to chemaxon/marvin/beans. The MarvinSketch bean is chemaxon.marvin.beans.MSketchPane, the MarvinView bean is chemaxon.marvin.beans.MViewPane.
The basic applet tag for MSketch and MView is simplified, and also generalized to work with or without Oracle's Java Plugin.
New file format: PDB (for simple, non-macro molecules)
Changes in template handling
The four template sets that come with Marvin became default. Templates only have to be specified as applet parameter if you need a different template set.
Templates moved to directory chemaxon/marvin/templates/ (from templates/).
File extension changed to .t (from .cssdf).
This change was required because of a Netscape restriction related to the loading of JAR file resources.
The JAR files marvin.jar and jmarvin.jar contain chemaxon/marvin/templates/generic.t, so the firewall problem ceased for the generic template set.
If needed, the additional templates may also be put into the JARs by the user with the JAR utility (part of Oracle's JDK). However, doing this increases the JAR size with a noticable amount.
The MolImport module moved into marvin.jar because of the firewall problem.
New query bond types: "single or double", "single or aromatic", "double or aromatic", "chain" and "ring".
SMARTS export handles the heteroatom (Q in molfile) type intelligently.
The heteroatom and the any atom types are specified in the queryAtoms parameter. The anyatom parameter became deprecated but is still present for backward compatibility, with slightly changed behavior. Specifying anyatom with any value (empty string also) is equivalent to specifying "any,hetero" in queryAtoms.
Cell selection in MarvinView can be controlled using the selectable parameter.
New methods in MarvinSketch: getBondlen. getMag, getPiece, getRescaling. New method in MarvinView: setSelectedIndex, The setDispopts method ceased to exist. Display options can be set using the dispopts applet parameter only.
In Marvin 2.2 and later, the Java classes come only in packaged forms: marvin.jar and marvin.zip. It means that support is ceased for those archaic Java-compatible browsers that cannot handle the ARCHIVE option in the applet tag (Netscape 2 and MS Explorer 3). Reasons:
Under certain circumstances, some Netscape versions try to load the class files one by one instead of using marvin.jar. The simplest way to keep Netscape from doing so is to remove the class files.
Most of our users don't understand what ARCHIVE is, and don't use it properly. The consequence is a significantly increased download time.
From now, a missing ARCHIVE option cannot be left unnoticed, because Marvin will simply not run. Much better than turning your user's hair gray.
Marvin is rarely tested in the oldest (and buggiest) browsers.
If you are absolutely sure that you want your Marvin page work with Netscape 2 and MS Explorer 3 too, you must unpack marvin.zip manually. However, we do not recommend this, because you will probably do something wrong. For example, once you will upgrade Marvin and forget to unpack the new marvin.zip. Mixing two different versions will result in malfunction.
Molecules in MarvinView are only editable if the editable applet parameter is set.
CML (XML) export.
The getSelectedIndex() method in MarvinView.
Default value of the rescaling parameter in MarvinSketch is changed to "mag" because generally this value is the most useful.
The MarvinView-only package ceased to exist, the new Edit/Structure function made it irrelevant.
Templates in MarvinSketch: From now on templates are stored in SDfiles (.sdf) or compressed SDfiles (.cssdf). The template file can be optionally compressed with GZIP, but the applet will only work in Java 1.1 compatible browsers in that case. The tmplmol, tmplpar, and ntmpls parameters no longer exist and are replaced by the much more easy to use tmpls parameters. The unit rotation angle can be specified as a new Marvin-specific property M MRV PHI in the template molecule files (instead of the tmplpar parameters).
Applet tags changed: Rewrite your applet tags according to the last solution in MarvinSketch Example 1 . This applet tag can load the AWT and the Swing applets as well.
Note that the file &{marvinjar}; is not packaged now (its name caused too many problems), so you must rewrite your applet tags, otherwise the download time with MS Explorer will not be optimal.
New in MarvinSketch: The menubar parameter enables or disables the menu bar in the Swing sketcher.
New in MarvinView: Molecules start rotating in 3D automatically if you set the animate parameter in MarvinView.
New in MarvinView:Border between cells in molecule tables.
Change in MarvinView: From now the colors can be specified in the same way as in MarvinSketch. Molecule background is molbg, normal table background is bgcolor. (Previously, bgcolor was also the molecule background.)
JavaScripter applet ceased to exist.
Its functionality is moved into a MarvinView module that is automatically loaded at the first js: action.
In the past, JavaScripter was required because scripting applets are not cached by older browsers (namely Netscape 3). An applet that has the MAYSCRIPT attribute is loaded from the net for each page that contains it. In Netscape 4 and later, there is no such problem. On the other hand, a bug (or feature?) in Netscape 4.6 makes the use of JavaScripter impossible as a separate applet. That's why we merged the two applets now.
New: Three new molecule file formats: "sybyl" (the SybylImport and SybylExport modules), "xyz" ( XyzExport ), and "pov" ( PovExport ).
New and changed: The "implicitH" option in the dispopts applet parameter instead of the showH parameter which ceased to exist.
"off" -> "implicitH=off"
"term" -> "implicitH=heteroterm" (because "term" ceased to exist)
"hetero" -> "implicitH=hetero"
"heteroterm" -> "implicitH=heteroterm" (default)
"all" -> "implicitH=all"
New features: if you want the explicit H atoms to be invisible, use "explicitH=off" (default: "all").
If you have 3D molecules, use "dim=3" for MarvinView, to let him know that you want 3D rotation as the default mouse drag action.
New: The atomStrings parameter enables the usage of atom aliases and SMARTS strings in the sketcher.
Incompatible change: The setAtoms, setNoatoms, setNobonds methods, and the atoms, noatoms, nobonds applet parameters ceased to exist and replaced by elements , anyatom, queryAtoms , and extraBonds .
New: The new detach parameter makes it possible to detach the sketcher from the web page immediately when the applet is loaded.
Recommended: In molfiles and compressed molfiles written directly in HTML, you should end all the molfile lines with backslash and also a real newline character like here:
...
000Wun+V70\
iuzV000W60\
iuzVGS2W60\
K72WGS2W60\
...Omitting the real newlines like in "000Wun+V70\iuzV000W60\iuzVGS2W60\K72WGS2W60\", seemed to be safe so far, while the Marvin applets were tested only in Oracle, Netscape, Symantec, and Microsoft JVM's. The reason for discontinuing this practice is that the AppletViewer in Kaffe 1.0b3 has problems if you write more than one molfile lines in one HTML line.
Removed: Backward compatibility with the old style (1.0-1.1) usage of getMol() and getM() removed. It didn't work with MSIE anyway.
Incompatible change: MSketch.getMol(x) and MView.getM(n,x).
In Marvin 1.1.4 and before, x was a boolean variable specifying the format of the generated molfile: MDL mol (false) or compressed mol (true).
From version 1.2, x is a format descriptor string to ease the introduction of new molecule file formats as Marvin evolves. MDL molfile format is denoted by the string "mol", compressed mol is "csmol", SMILES is "smiles".
New: The preload applet parameter.
"Extra features" are planned to be available as external modules in future releases of Marvin. External modules are downloaded only when needed. In Marvin 1.2.3, MDL mol, compressed mol and SMILES export are external modules.
The problem is that older browsers such as Netscape 3, cannot load the external modules when the module is needed by a public method which is called from JavaScript. So if you want your web page containing Marvin to work perfectly with earlier releases of Netscape than 4, then you should preload all the modules which may be needed by JavaScript calls.
For example, if you are using MSketch.getMol("smiles") on your page, then you should also have the following applet parameter:
<param NAME="preload" VALUE="SmilesExport">.
