NAME

       gmx-rama - Compute Ramachandran plots

SYNOPSIS

          gmx rama [-f [<.xtc/.trr/...>]] [-s [<.tpr>]] [-o [<.xvg>]] [-b <time>]
                   [-e <time>] [-dt <time>] [-[no]w] [-xvg <enum>]

DESCRIPTION

       gmx  rama  selects  the  phi/psi  dihedral  combinations  from your topology file and computes these as a
       function of time.  Using simple Unix tools such as grep you can select out specific residues.

OPTIONS

       Options to specify input files:

       -f [<.xtc/.trr/...>] (traj.xtc)
              Trajectory: xtc trr cpt gro g96 pdb tng

       -s [<.tpr>] (topol.tpr)
              Portable xdr run input file

       Options to specify output files:

       -o [<.xvg>] (rama.xvg)
              xvgr/xmgr file

       Other options:

       -b <time> (0)
              Time of first frame to read from trajectory (default unit ps)

       -e <time> (0)
              Time of last frame to read from trajectory (default unit ps)

       -dt <time> (0)
              Only use frame when t MOD dt = first time (default unit ps)

       -[no]w (no)
              View output .xvg, .xpm, .eps and .pdb files

       -xvg <enum> (xmgrace)
              xvg plot formatting: xmgrace, xmgr, none
