g_dih1

Analyzes dihedral transitions version 4.5.4-dev-20110404-bc5695c

Usage

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

Overview

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.
