     obabel -- a converter for chemistry and molecular modeling	data files

     obabel [-H	help-options]
     obabel [OPTIONS] [-i input-type | -: "SMILES-string"] infile
	    [-o	output-type] -O	outfile

     obabel 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 chem-
     istry software. For more information, se the Open Babel web pages

     If	only input and output files are	given, Open Babel will guess the file
     type from the filename extension.

     -:	"SMILES-string"
	   Enter SMILES	string and use it in place of an input file. The
	   SMILES string should	be enclosed in quotation marks.	More than one
	   can be used,	and a molecule title can be included if	enclosed in

     -a	options
	   Format-specific input options. See -H format-ID for options allowed
	   by a	particular format

	   Append text to the current molecule title

	   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	#  For multiple	entry input, start import with molecule	# as the first

     -F	   Output the available	fingerprint types

     -h	   Add hydrogens

     -H	   Output usage	information

     -H	format-ID
	   Output formatting information and options for format	specified

	   Output formatting information and options for all formats

	   Specifies input format, see below for the available formats


	   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 consec-
		     utively numbered output files
		 -   Batch conversion -	convert	each of	multiple input files
		     into a specified output format

     -l	#  For multiple	entry input, stop import with molecule # as the	last

     -o	format-ID
	   Specifies output format, see	below for the available	formats

     -O	outfile
	   Specify the output file. This option	applies	to obabel only.

     -p	   Add Hydrogens appropriate for pH (use transforms in phmodel.txt)

	   Add or replace a property (e.g., in an MDL SD file)

     -s	SMARTS
	   Convert only	molecules matching the SMARTS pattern specified

	   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	al-
	   lowed 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
