NAME

       g_dih - analyzes dihedral transitions

       VERSION 4.0.1

SYNOPSIS

       g_dih -f traj.xtc -s topol.tpr -o hello.out -[no]h -nice int -b time -e
       time -dt time -[no]w -[no]sa -mult int

DESCRIPTION

       g_dih can do two things. The default is to analyze dihedral transitions
       by  merely  computing  all the dihedral angles defined in your topology
       for the whole trajectory. When a dihedral flips over to another minimum
       an angle/time plot is made.

       The  opther option is to discretize the dihedral space into a number of
       bins, and group each conformation in dihedral space in the  appropriate
       bin.  The  output  is  then given as a number of dihedral conformations
       sorted according to occupancy.

OTHER OPTIONS

       -[no]hno

       -nice int 19
        Set the nicelevel

       -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)

        View output xvg, xpm, eps and pdb files

       -[no]sano
        Perform cluster  analysis  in  dihedral  space  instead  of  analysing
       dihedral transitions.

       -mult int -1
        mulitiplicity for dihedral angles (by default read from topology)
