detChirality

detChirality

Determine the chirality of centers in the specified PDB file.

Usage: detChirality [options] <pdb file>

where options are one or more of:

-psf <file.psf>         - psf file- required.
-par <file.par>         - load parameters to help in determining bond order.
-bondOrder <file.bo>    - load explicitly defined bond order information.
                          This file consists of entry lines taking form:
                                   double name1 name2
                                   triple name1 name2
                          where name1 and name2 are atom names. By default all
                          bonds are single bonds, so they do not need to be
                          specified.
-centers <vals>         - a space- or colon-separated list of atom names
                          specifying the the chiral centers to the queried.
                          By default, this list consists of all carbon
                          atoms.
-anchored               - If this flag is not specified, the absolute
                          chirality is chosen to optimize the match with the
                          first structure. If this is set, absolute chirality
                          is not changed.
