NAME
obgrep - an advanced molecular search program using SMARTSSYNOPSIS
[OPTIONS ] 'SMARTS-pattern' filenameDESCRIPTION
The obgrep tool can be used to search for molecules inside multi-molecule database files (e.g., SMILES, SDF, etc.) or across multiple files.OPTIONS
If only a filename is given, obgrep will attempt to guess the file type from the filename extension.- -c
- Print the number of matches
- -f
- Full match, print matching-molecules only when the number of heavy atoms is also equal to the number of atoms in the SMARTS pattern
- -i format
- Specifies input and output format, see babel(1) for available formats
- -n
- Only print the name of the molecules
- -t file ...
- Print a molecule only if the pattern occurs # times inside the molecule
- -v
- Invert the matching, print non-matching molecules
EXAMPLES
Note that in all examples, the SMARTS pattern is enclosed in single quotes '...' to ensure it is not changed by the shell.Print all the molecules with a methylamine group:
"obgrep 'CN' database.smi"
Print all the molecules without a methylamine group:
"obgrep -v 'CN' database.smi"
Print the number of molecules without a methylamine group:
"obgrep -v -c 'CN' database.smi"
Print methylamine (if it exists in the file):
"obgrep -f 'CN' database.smi"
Print methylamine and/or methanol (if they exist):
"obgrep -f 'C[N,O]' database.smi"Print all molecules with aromatic carbon in all SMILES files in the directory (i.e., *.smi)
"obgrep 'c' *.smi"
