NAME

babel - a converter for chemistry and molecular modeling data files

SYNOPSIS

[-H help-options ]
[OPTIONS ] [-i input-type ] infile [-o output-type ] outfile

DESCRIPTION

Babel is a cross-platform program designed to interconvert between many file formats used in molecular modeling and computational chemistry and related areas.

Open Babel is also a complete programmers toolkit for developing chemistry software. For more information, se the Open Babel web pages <http://openbabel.org/>.

OPTIONS

If only input and ouput files are given, Open Babel will guess the file type from the filename extension.
-a options
Format-specific input options. See -H format-ID for options allowed by a particular format
--addtotitle
Append text to the current molecule title
--addformula
Append the molecular formula after the current molecule title
-b
Convert dative bonds: e.g., [N+]([O-])=O to N(=O)=O
-c
Center atomic coordinates at (0,0,0)
-C
Combine molecules in first file with others having the same name
-e
Continue after errors
-d
Delete Hydrogens
---errorlevel 2
Filter the level of errors and warnings displayed:

       1 = critical errors only
       2 = include warnings too (default)
       3 = include informational messages too
       4 = include "audit log" messages of changes to data
       5 = include debugging messages too
-f file ...
For multiple entry input, start import with molecule # as the first entry
-F
Output the available fingerprint types
-h
Add hydrogens
-H
Output usage information
-H format-ID
Output formatting information and options for format specified
-Hall
Output formatting information and options for all formats
-i<format-ID>
Specifies input format, see below for the available formats
-j
--join
Join all input molecules into a single output molecule entry
-k
Translate computational chemistry modeling keywords (e.g., GAMESS and Gaussian)
-m
Produce multiple output files, to allow:
Splitting one input file - put each molecule into consecutively
numbered output files
Batch conversion - convert each of multiple input files into a
specified output format
-l file ...
For multiple entry input, stop import with molecule # as the last entry
-o format-ID
Specifies output format, see below for the available formats
-p
Add Hydrogens appropriate for pH (use transforms in phmodel.txt)
--property
Add or replace a property (e.g., in an MDL SD file)
-s SMARTS
Convert only molecules matching the SMARTS pattern specified
--separate
Separate disconnected fragments into individual molecular records
-t
All input files describe a single molecule
--title title
Add or replace molecular title
-x options
Format-specific output options. See -H format-ID for options allowed by a particular format
-v SMARTS
Convert only molecules NOT matching SMARTS pattern specified
-V
Output version number and exit
-z
Compress the output with gzip

FORMAT OPTIONS

Individual file formats may have additional formatting options.

Input format options are preceded by 'a', e.g. -as

Output format options are preceded by 'x', e.g. -xn

For further specific information and options, use -H<format-type>

 e.g., -Hcml

EXAMPLES

Standard conversion:
"babel -ixyz ethanol.xyz -opdb ethanol.pdb"
Conversion from a SMI file in STDIN to a Mol2 file written to STDOUT:
"babel -ismi -omol2"
Split a multi-molecule file into new1.smi, new2.smi, etc.:
"babel infile.mol new.smi -m"
