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.

Portable xdr run input file
Options to specify output files:
-o [<.xvg>] (rama.xvg)
xvgr/xmgr file
Other options:
-b <time> (0)
First frame (ps) to read from trajectory
-e <time> (0)
Last frame (ps) to read from trajectory
-dt <time> (0)
Only use frame when t MOD dt = first time (ps)
-[no]w (no)
