g_hbond not running
Hi, have run various vacuum simulations with GROMACS 4.6.7. I find I can calculate h-bonds using g_hbond -f md.trr -s md.tpr on some simulations just fine while on others the system freezes 'Frame loop parallelized with OpenMP using 32 threads' even after leaving > 12 hours there is no progress or error. I have not found this problem on the web nor been able to sort out myself. I have tried various -nthreads flags including 1 and it wont budge. I get no error report it just freezes -> any insight would be most appreciated.
