Hey everyone, <br>I wrote a few days ago about a segmentation fault I'm getting from grompp when I try to set up a membrane protein system. Grompp opens the ff_dum.itp file and then the core dumps immediately. This happens on two different machines, both of which are running gromacs 4.0.5. <br>
<br>I just downloaded lipid.itp, popc128a.pdb and popc.itp fresh from Tieleman's website, made a topology file and tried running grompp on it. I still get the same segmentation fault. However, when I run the same files through grompp from gromacs 3.3, it works fine. Has anyone else seen this problem, or is it just me? What can I do to find and fix the problem? <br>
<br>Thanks<br>Gard Nelson<br>
