obgrep(1) User's Reference Manual obgrep(1)NAMEobgrep -- an advanced molecular search program using SMARTSSYNOPSISobgrep [OPTIONS] 'SMARTS-pattern' filenameDESCRIPTIONThe obgrep tool can be used to search for molecules inside multi-molecule database files (e.g., SMILES, SDF, etc.) or across multiple files.OPTIONSIf 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 # Print a molecule only if the pattern occurs # times inside the molecule -v Invert the matching, print non-matching moleculesEXAMPLESNote 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' *.smiSEE ALSObabel(1), obfit(1), obrotate(1).
