H, +H |
Add explicit Hydrogen atoms. |
-H |
Remove explicit Hydrogen atoms. |
A |
Atom attributes are stored in arrays. For 2D molecules, only the x, y coordinates are stored. This is a more compact form of storage than the default (using <atom> tags). |
P |
Create human readable output: put new XML elements in new lines and indent for embedded elements. |
CN |
The accuracy of the exported coordinates can be given: N is the length of the decimals of the coordinate, 0 < N ≤ 9 |
D |
This option is important if the molecule has parity information and has 0 dimension. By default during the export, a clean method is invoked on the structure and the generated coordinates and wedge information are exported into CML format but NOT the parity information. However, using this option coordinates and wedge information are not generated but parity information is exported. |
I |
Ignore unexportable molecule properties. Without this option the exporter will throw an exception when reach an unexportable property. |
BOM |
Write the UTF-8 byte order mark (BOM), if the given or the system's encoding is UTF-8. |
For example: cml:A or cml:C5.

Explanation |
Xsg |
Expand all S-groups. |
Usg |
Ungroup all S-groups. |
Fsg |
Ungroup S-groups with 3 or more attachment points. |
bXXX |
Set the C-C bond length used in the molfile. The molecule file is supposed to store coordinates in 1.54Å/XXX units. Marvin uses Å units internally, thus coordinates are rescaled by factor 1.54/XXX at import if XXX is a nonzero number. If XXX = 0, then coordinates are not rescaled (default setting for 3D molecules if option 'b' is not used). If XXX = A, then coordinates are rescaled to transform the molfile's average C-C bond length to 1.54 Å (default setting for 2D molecules). Examples: "caffeine.mol{b0}" or "caffeine.mol{b1.54}" (bond lengths are in angstroms), "caffeine.mol{b0.825}" (bond lengths are in ISISDraw's units), "caffeine-V3.mol{bA}" (average bond length calculation, same as default). |
nomolp |
Read molecule type data fields ($DTYPE $MFMT and $RFMT in RDfiles) as strings instead of Molecule objects. |
skipMMRV |
Neglect ChemAxon/Marvin specific lines in the properties block. Such lines are in the following format: M MRV ... They should be skipped if the file is converted with non-ChemAxon software, which preserved them but made them invalid, e.g. by changing the total number of atoms and bonds. |
skipAtomValue |
Disables the import of "Atom values" from the given ctfile. |
z |
Carbon atoms with "Z" as alias string are converted to R-group attachment points. |

V2 or V3 |
Force writing V2 or V3 (extended) molfiles. The default format is V2 for simple molecules, V3 if the number of atoms or bonds exceeds 999, in case of reactions with Rgroups or there is enhanced stereo in the molecule. |
mol:V3 |
P |
Write floating point numbers with maximum precision. Only meaningful for V3 molfiles. |
mol:V3P |
bXXX |
Set C-C bond length. If XXX is nonzero, then the exported atom coordinates are rescaled by XXX / 1.54. If XXX = 0, then coordinates are not rescaled. |
|
ec |
Convert to enhanced stereo representation, considering the chiral flag. Only meaningful with option V3. (Chiral centers are grouped into ABS or an AND stereo group, depending on the chiral flag. When the input molecule contained any enhanced stereo labels, the unlabeled stereo centers always will form a new AND group.) |
mol:V3ec |
ea |
Convert to enhanced stereo representation, assuming absolute stereochemistry. Only meaningful with option V3. (Chiral centers are grouped into the ABS group. In case the input molecule already contains enhanced stereo labels, the behaviour is similar to the one described at option ec above.) |
mol:V3ea |
cc |
Write CHIRAL flag if there are only ABS enhanced stereo labels in the molecule. Only meaningful with option V2. |
mol:V2cc |
omitClean0D |
Omits the clean operation while exporting 0D molecules into ctfile format with V2 compatibility which is the default. This clean was introduced in 5.4 because the ctfile format cannot contain stereo information without coordinates. |
mol:omitClean0D |
BOM |
Write the UTF-8 byte order mark (BOM), if the given or the system's encoding is UTF-8. |
mol:BOM |
Import options
--smiles string |
Read molecule from specified SMILES string |
|
--smarts string |
Read molecule from specified SMARTS string |
|
f {fFIELD1,fFIELD2,...} |
Import data fields from a multi-column file. The fields should be separated by tab character. The first column contains the SMILES/SMARTS strings, the second may contain the molecule name or the data field called FIELD1, the following columns contain the other fields. |
molconvert sdf "foo.smi{fname,fID}" reads the smiles string, the name and the ID from the foo.smi file and converts it to SDF format. |
d |
Import with Daylight compatibility for query H. |
|
c |
Ignore fixing of double bond stereo information in small rings, also ignore fixing of aromatic bonds to aliphatic if necessary. |
|
Z |
Import compressed smiles. The compressed format must be specified explicitly, as it is not recognized by the importer automatically. |
|
After importing SMILES, invoking of MoleculeGraph.clearCashedInfo method is recommended in order to remove cashed information which results increased molecule size.
Export options
Export options can be specified in the format string. The format descriptor and the options are separated by a colon.

Explanation |
t |
converts to traditional name. This option generates a common name if one is known for the structure. Otherwise, it generates a systematic name, but sometimes uses some traditionally accepted rules instead of the strict application of the IUPAC rules, when that generates a simpler name. |
i |
converts to IUPAC name (default). |
common |
generates the most popular common name of a structure. (It fails if none is known.) |
common,all |
generates all common names of a structure. |
source |
outputs the name present in the source data (no generation). |
CAS# |
Fetches the CAS Registry Number(s) of the structure, using a public internet webservice. In case the structure corresponds to several CAS Registry Numbers, they are all returned, separated by commas. |
singleCAS# |
Fetches the CAS Registry Number of the structure, using a public internet webservice. In case the structure corresponds to several CAS Registry Numbers, the lowest one (historically assigned earlier) is returned. |
ascii |
Use only ASCII characters to encode the name. |
timeout=<N> |
Use at most N seconds for the name to be computed. The default timeout is currently 20 seconds (which should normally be reached exceptionally, for very large structures). A value of 0 means no timeout. |

-common |
disable conversion of common names (such as aspirin) |
-elements |
disable conversion of the name of chemical elements, for instance carbon, sodium, .... Even though "carbon" is not converted, "methane" still is, since it is a molecule name for CH4, not an element. |
-ions |
disable conversion of atomic ion syntax, for instance "Ca2+". |
-groups |
disable conversion of groups and fragments, such as "oxo" or "methyl". |
-cas |
disable the conversion of CAS registry numbers |

dict=PATH |
specify the location of the custom dictionary. Example: name:dict=C:\Users\Me\MyDictionary.smi. |
webservice=URL |
enable the usage of a custom webservice at the given URL |
Some of these options are mainly useful when configuring which names Document to Structure recognizes.
To enable an option, a + sign can be used before the option name. For instance, both forms ocr and +ocr are accepted to enable this option.
code:csv
Basic information about the format
CSV stands for "coma separated value" and it is very simple molecule format.
id,mol,registeting_user,note
1,C,[email protected],this is a rather common element
2,[H],[email protected],"I bet this is more common, how could you miss it?"
3,[He],[email protected],This is boring il ne reagit pas avec quoi que ce soit!
In this file we have 3 molecules, and every of them has the following information:
-
ID
-
registering_user
-
note
The molecule sources are in smiles. After import we get the following structures and properties:
-
A simple Carbon, with:
-
ID = 1
-
registering_user = [email protected]
-
note = this is a rather common element
-
-
A simple Hydrogen, with:
-
ID = 2
-
registering_user = [email protected]
-
note = I bet this is more common, how could you miss it?
-
-
A simple Helium, with:
-
ID = 3
-
registering_user = [email protected]
-
note = This is boring il ne reagit pas avec quoi que ce soit!
-
But the user can specify molecule during import which header to use. For example this file:
id,CHEMICAL_DATA,name
1,c1ccccc1CC(N)C,amphetamin
2,c1ccccc1,benzene
Can be imported with the following settings:
csv:strucCHEMICAL_DATA
With this MolImporter recognise that CHEMICAL_DATA filed holds the structure.
Import options
Headers
Automatically recognized molecule headers
Molecule can have any ChemAxon supported formats, but they must be written in one line. The recognized molecule headers are:
-
mol
-
molecule
-
structure
-
struc
-
smiles
-
cxsmiles
-
smarts
-
cxsmarts
-
inchi
User defined header
User can define which header to use as identifier of the molecule column when importing structure. This can be done with the "struc" parameter.
For example this file:
id,CHEMICAL_DATA,name
1,c1ccccc1CC(N)C,amphetamin
2,c1ccccc1,benzene
Can be imported with the following settings:
csv:strucCHEMICAL_DATA
With this MolImporter recognise that CHEMICAL_DATA filed holds the structure.
Headless import
User can import CSV molecules without header, in this case csv importer must be informed that all rows are data (for this use "headless" keyword), and the which colum has the chemical structure. This can be done by defining the zero-based index of the structure column. For example the following file
7,12,4,ccCCcc,rt,gh,jk
23,1,56,COO,rf,gg,kk
Can be imported as:
csv:headless,struc3
This would import the following structure:
-
ccCCcc (as smiles) with the following properties:
-
column_0 = 7
-
column_1 = 12
-
column_2 = 4
-
column_3 = rt
-
column_4 = gh
-
column_5 = jk
-
-
COO (as smiles) with the following properties:
-
column_0 = 23
-
column_1 = 1
-
column_2 = 56
-
column_3 = rf
-
column_4 = gg
-
column_5 = kk
-
Override column names
During import user can dynamically ovverride column names. For this he has to set the names in order. (Every definition starts with an "f" and spearated by coma".) For example this file:
result,hour
S.[He],11:15:00
[He],11:10:00
can be imported as:
-
S.[He]
-
TIME = 11:15:00
-
-
[He]
-
TIME = 11:10:00
-
With the following params:
csv:fMOL,fTIME
In the above example the renamed headers contained an autoreconizable header name, so we did not have to specifiy molecule colum. But this can be than as it is described in Header section with the "struc" keyword.?
Molecule format
User can specify what is the format of the molecules in the molecule comulmn with the "input" keyword. For example fro names use:
csv:inputname
Export options
Define Molecule column name:
User can set the name of the molecule column with "struc" keyword, like:
csv:strucMY_MOL_COLUMN
Define headless export
User can export molecules without headers with the "headless" keyword, like:
csv:headless
Define export format
User can define which format to use when export molecule with the "format" keyword, like:
csv:formatsmarts
Define exported column header names
It is possible to define the name of the exported clumns every name must start with an "s" like:
csv:sname,smol,suser

Import a file as XYZ, do not try to recognize the file format:
molconvert smiles
"foo.xyz{xyz:}"
Note: This is just an example. XYZ and other formats known by Marvin are always recognized (send us a bug report otherwise), so the specification of the input format is usually not needed. It is only relevant if a user-defined import module is used.
-
Import a file as XYZ, with bond-length cut-off = 1.4, and max. number of Carbon connections = 4, export to SMILES:
molconvert smiles
"foo.xyz{f1.4C4}"
-
Import a file as Gzipped XYZ, with the same import options as in the previous example:
molconvert smiles
"foo.xyz.gz{gzip:xyz:f1.4C4}"
-
Like the previous example but merge the molecules into one molecule that contains multiple atom sets. MDL molfile is exported.
molconvert mol
"foo.xyz.gz{gzip:xyz:MULTISET,f1.4C4}"
-
Import an SDF and export a table containing selected molecules with columns: SMILES, ID, and logP:
molconvert smiles -c
"ID<=1000&logP>=-2&logP<=4"
-T ID:logP foo.sdf
-
Fuse R2 definition from file, filter fragments with 1 attachment point:
molconvert mrv in.mrv -R2:
1
rdef.mrv
-
Fuse fragments from file (note, that the input molecule, which the fragments are fused to, should also be specified):
molconvert mrv in.mrv -R frags.mrv
-
Generate all common names for a structure:
molconvert
"name:common,all"
-s tylenol
-
Generate the most popular common name for a structure (It fails if none is known.):
molconvert name:common -s viagra
-
Generate SMILES from those molecules that names are mentioned in a file foo.html:
molconvert smiles foo.html
