g_dih: analyzes dihedral transitions

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.

FILES
