g_disre - analyzes distance restraints


g_disre -s topol.tpr -f traj.xtc -ds drsum.xvg -da draver.xvg -dn drnum.xvg -dm drmax.xvg -dr restr.xvg -l disres.log -n viol.ndx -q viol.pdb -c clust.ndx -[no]h -nice int -b time -e time -dt time -[no]w -[no]xvgr -ntop int


g_disre computes violations of distance restraints. If necessary all protons can be added to a protein molecule using the protonate program.

The program allways computes the instantaneous violations rather than time-averaged, because this analysis is done from a trajectory file afterwards it does not make sense to use time averaging. However, the time averaged values per restraint are given in the log file.

An index file may be used to select specific restraints for printing.

When the optional -q flag is given a pdb file coloured by the amount of average violations.

When the -c option is given, an index file will be read containing the frames in your trajectory corresponding to the clusters (defined in another manner) that you want to analyze. For these clusters the program will compute average violations using the thisd power averaging algorithm and print them in the log file.
