[gmx-users] Problem in implementing do_dssp

[Sarath Chandra]

do_dssp is looking for /usr/local/bin/dssp and if your dssp executable has
some other name do_dssp will fail.

Before you run do_dssp you need to set the DSSP variable.

for bash environment do this:

export DSSP=`which dssp-2.0.4-linux-amd64`

Regards,

Sarath
