Problem in dssp file

GROMACS version:2020.3
GROMACS modification: No
I want to analyze secondary structure by Dssp package in gromcas. I did it while the value of x and y axis is weird(the number of amino acids and time showed as zero value). I change the scale of x and y axis by -by and -bx in command "gmx xpm2ps -f ss.xpm -o ss.eps -by 1 -bx 0.06 " but it did not correct. I did not know how to correct it. could you help me with this issue? i will send the picture of my Dssp output file.

A number of similar bugs in xpm2ps/do_dssp have been fixed in subsequent versions of gromacs. You may want to try this analysis again with the latest version.
