Hi Shahid,

I have fixed the problem in do_dssp. You can either pull the
newest release-4-0-patches branch from the git repository
or change ./src/tools/do_dssp.c, line 80 from

snew(ssbuf,nres+10); 

to:

snew(ssbuf, 2*nres-1);

I though this problem was because of the executible in /usr/local/bin/ and rest of file in another directory say /home/shahid/software/dssp/. For this first I set the path in ~/.bascrc

It ultimately doesn't matter where your executable is, /usr/local/bin is default, but you can set any other location you like with the DSSP environment variable.
