         [-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.

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

-dt <time> (0)
