Non-uniform DSSP Scale

GROMACS version: 2020.4
GROMACS modification: No

Below is my .eps file that I got by running DSSP. As you can see, the tick marks on the x-axis is not uniform, and numbers and legends overlap.
I have tried changing the size of the matrix elements and nth frames where major and minor ticks are located, but none of them solved the problem.

It worked fine when I was using Gromacs 2018.3 version, but after switching to 2020.4, this happened.
Anyone who has used DSSP and run into the same problem, a help will be appreciated. Thank you.


maybe gmx xpm2ps ( can be help you in the visualization xpm file. You can also provide an .m2p parameter file, with the desired options

Best regards

Thank you for your reply.
Below is the .m2p file I have been using. I tried changing “xbox”, “x-major”, and “x-minor” values, which didn’t work.
I am not quite sure why the number of the x-axis starts with 250, then 300, and drop to 100 and so on.
Plus, a lot of 0’s are there as well, with the shrunk legend.
Maybe there’s something wrong with my system? or does it have to do with compatibility of this version of Gromacs with DSSP? Not quite sure…
