SYNOPSISg_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
DESCRIPTIONg_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.

Perform cluster analysis in dihedral space instead of analysing dihedral transitions.
-mult int -1
