[gmx-users] Installing DSSP

[soumadwip ghosh]

Hello all,

I am trying to install dssp in centos 7 for determining the secondary
structure of a protein in combination with do_dssp. These are the steps I
followed:

1. installation directory : /opt/apps/dssp/dssp-2.2.1/

2. but there is no dssp executable in the dssp-2.2.1 directory

3. however there was a dssp.o file in the obj directory of dssp-2.2.1

4. we renamed the dssp.o file to dssp and moved it to dssp-2.2.1 directory

5. ln -s /opt/apps/dssp/dssp2.2.1/dssp /usr/local/bin/

6. export dssp=/usr/local/bin/dssp



but inspite of executing the above steps, when we run the do_dssp command we get
the following error : Fatal error: DSSP executable
(usr/local/bin/dssp/dssp) does
not exist (use setenv DSSP)

PS. we are using bash


I have read various threads on the errors related to do_dssp but could
not find a solution.

Any kind of help would be appreciated.


Best,
