.SH NAME
gmx-mk_angndx \- Generate index files for 'gmx angle'

.SH SYNOPSIS
gmx mk_angndx [\-s [<.tpr/.tpb/...>]] [\-n [<.ndx>]] [\-nice <int>]
             [\-type <enum>] [\-[no]hyd] [\-hq <real>]

.SH DESCRIPTION
\fBgmx mk_angndx\fR makes an index file for calculation of angle distributions etc. It uses a run input file (\fB.tpx\fR) for the definitions of the angles, dihedrals etc.

.SH OPTIONS
Options to specify input and output files:

.BI "\-s" " [<.tpr/.tpb/...>] (topol.tpr) (Input)"
    Run input file: tpr tpb tpa

.BI "\-n" " [<.ndx>] (angle.ndx) (Output)"
    Index file


Other options:

.BI "\-nice" " <int> (0)"
    Set the nicelevel

.BI "\-type" " <enum> (angle)"
    Type of angle: angle, dihedral, improper, ryckaert\-bellemans

.BI "\-[no]hyd" "  (yes)"
    Include angles with atoms with mass  1.5

.BI "\-hq" " <real> (-1)"
    Ignore angles with atoms with mass  1.5 and magnitude of their charge less than this value
