[gmx-users] segmentation fault : g_sas

[Madhuri Agashe]

Hi,
I am trying to analyze the solvent accessible areas for a protein after
running molecular dynamics on it.
I used the following command:

g_sas -f 2.trr -s 2.tpr -o area.xvg -r resarea.xvg -n 3.ndx

I always get the following output for this:

Opening library file /usr/local/share/gromacs/top/dgsolv.dat

-------- -------- --- Thank You --- -------- --------

3987 out of 70695 atoms were classified as hydrophobic

Back Off! I just backed up area.xvg to ./#area.xvg.3#
frame:     0Segmentation fault


Is this segmentation fault due to some error in any of the input files? Or
is there some problem with this command?

Thanks,
Madhuri
