gmx mk_angndx [-s [<.tpr>]] [-n [<.ndx>]] [-type <enum>] [-[no]hyd]
             [-hq <real>]


gmx mk_angndx makes an index file for calculation of angle distributions etc. It uses a run input file (.tpx) for the definitions of the angles, dihedrals etc.


Options to specify input files:

-s [<.tpr>] (topol.tpr)

Portable xdr run input file

Options to specify output files:

-n [<.ndx>] (angle.ndx)

Index file

Other options:

-type <enum> (angle)

Type of angle: angle, dihedral, improper, ryckaert-bellemans

-[no]hyd (yes)
