[gmx-users] DSSP Error

[masoud keramati]

Hi to all

first i run 'gmx do_dssp -s md.tpr -f md.xtc' i  go this error:
Fatal error:
DSSP executable (usr/local/bin/dssp) does not exist (use setenv DSSP)

then i put dssp executable file in the path 'usr/local/bin/dssp'
and run following command : 'export DSSP=/usr/local/bin/dssp'
now when i run gmx do_dssp i get this error: 'Fatal error:
Failed to execute command: Try specifying your dssp version with the -ver
option.'
even with use of-ver option, i got the same error.
what can i do to solve this problem?

thanks for your help
