[gmx-users] Structure averaging problem using g_rmsf

[Spring buds]

Hi

I am trying to average the structure from the last 10ns from 100ns. So I
used the command which is below:

g_rmsf –f 100.xtc –s topol.tpr –b 90001 –e 100000 –ox traj_avg.pdb

But I got below error:

"Program g_rmsf, VERSION 4.5.4
Source code file: /root/Desktop/gromacs-4.5.4/src/gmxlib/trxio.c, line: 713

Fatal error:
Specified frame doesn't exist or file not seekable"

I searched the forum before posting it but I am not.

Thank you
