Thanks for the fast reply.
I'm only trying to monitor the hbond formation with the " basic" command
g_hbond -f m93_newtraj.trr -s topol.tpr -n
and giving to the groups selection two different parts of my protein (i've made an index file)..and then the programs suddenly stop.
the default output (-num) should be the total number of hbond per frame.
Please help me again
