Hello, do_dssp (4.5.5) is broken. There are two possible answers you're gonna get here:
1) Use old dssp, which you are using. 2) You're an idiot, which are not. What I did to solve the problem was, download gmx from git, and substitute the /src/tools/do_dssp.c of gmx 4.5.5 with the one from the git version. Re-compile it and voila! This do_dssp version accepts both old and new dssp and you have to specify which version with the flag -ver if I remember correctly. This worked perfectly for me. I hope it helps you as well. All the best, João Henriques On Mon, Nov 12, 2012 at 8:38 AM, mshappy1986 <mshappy1...@126.com> wrote: > Hi all, > I am meeting the following error in Gromacs 4.5.5 with do_dssp > Here is the command > do_dssp -f md.xtc -s md.tpr -o dssp.xpm > give me the following error > segmentation fault > I have downloaded the executable DSSP form > http://swift.cmbi.ru.nl/gv/dssp/ and set the environment variable, but > do_dssp did not work. > How can I fix it? > Thanks a lot > > > > > > > > > > > -- > gmx-users mailing list gmx-users@gromacs.org > http://lists.gromacs.org/mailman/listinfo/gmx-users > * Please search the archive at > http://www.gromacs.org/Support/Mailing_Lists/Search before posting! > * Please don't post (un)subscribe requests to the list.
