You probably need to set -ver appropriately in your do_dssp command.

I google it and found this on ubuntu forum but I followed it and still I am 
getting error

accept DSSP is not in official ubuntu repositories, but you can install it 
manually:
sudo wget ftp://ftp.cmbi.ru.nl/pub/software/dssp/dssp-2.0.4-linux-amd64 -O 
/usr/local/bin/dssp
or
sudo wget ftp://ftp.cmbi.ru.nl/pub/software/dssp/dssp-2.0.4-linux-i386 -O 
/usr/local/bin/dssp
And for the end:
sudo chmod a+x /usr/local/bin/dssp

   I have done this but still I am getting Fatal error: DSSP executable 
(/opt/dssp/bin/dssp) does not exist (use setenv DSSP) –

If you have set the $DSSP environment variable to point to /opt/dssp/bin/dssp, then you should get a fatal error, because based on the above commands, your dssp is in /usr/local/bin/dssp, which is the default location where do_dssp looks for it. If $DSSP is set, it overrides the default, which in your case is causing problems.

  Also appreciate if any one can give simple and step-by step instruction to 
insall dssp-2.2.1 from website. I mean after downloading dssp-2.2.1.tgz and 
extracting it what should I do? –


Unzip the archive, compile from source if you are downloading source (ignore if you are downloading a binary), move the binary wherever you want it, set $DSSP only if you are not putting it in /usr/local/bin.
