.Dd Oct 10, 2019 .Os "Open Babel" 3.1 .Dt obrotamer 1 URM .Sh NAME .Nm obrotamer .Nd "generate conformer/rotamer coordinates" .Sh SYNOPSIS .Nm .Ar filename .Sh 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. .Sh EXAMPLES .Dl "obrotamer baseconformer.sdf > rotamer1.sdf" .Pp Generate a random rotational isomer of baseconformer.sdf and write it to rotamer1.sdf .Sh SEE ALSO .Xr obabel 1 , .Xr obenergy 1 , .Xr obfit 1 , .Xr obgrep 1 , .Xr obminimize 1 , .Xr obrotate 1 . .Pp The web pages for Open Babel can be found at: \%<\fBhttp://openbabel.org/\fR> .Sh AUTHORS .An -nosplit Open Babel is developed by a cast of many, including currrent maintainers .An Geoff Hutchison , .An Chris Morley , .An Michael Banck , and innumerable others who have contributed fixes and additions.
