obrotamer(1) General Commands Manual (urm) obrotamer(1) NAME obrotamer - generate conformer/rotamer coordinates SYNOPSIS obrotamer filename DESCRIPTION The obrotamer tool can be used as part of a conformational search by generating random isomers based on rotating dihedral angles. These rotamers are not conformers -- that is, obrotamer does not perform geometry optimization after generating the rotamer structure. The obminimize tool can do geometry optimization using molecular mechanics. EXAMPLES obrotamer baseconformer.sdf > rotamer1.sdf Generate a random rotational isomer of baseconformer.sdf and write it to rotamer1.sdf SEE ALSO obabel(1), obenergy(1), obfit(1), obgrep(1), obminimize(1), obrotate(1).
