Hi all,
I'm beginning to analyze my trajectories, everything works fine with
(g_rmsf, g_saltbr ...) but when i try to use g_hbond I receive this
Program g_hbond, VERSION 3.3.1
Source code file: gmx_hbond.c, line: 631

Fatal error:
Your computational box has shrunk too much.
g_hbond can not handle this situation, sorry.

Is this a bug or a problme with my system? Is there the possibility to
avoid this problem in some way?
