[gmx-users] Regarding DSSP

[HANNIBAL LECTER]

Thanks Justin. So as I mentioned, I am using Gromacs-4.5.6 and there is not
a scope to specify using the -ver command in this particular version as
opposed to the newer versions (5.0.4).

By '....' I meant

do_dssp -f prot.xtc -s prot.tpr.

How do I specify a dssp version in gromacs-4.5.6?

Secondly, I did install Gromacs-5.0.4 for comparison, and I am using DSSP
2.0.4 again. This time I am using

do_dssp -f prot.xtc -s prot.tpr -ver 2

The output I am getting is shown below. Not sure what is going on.
