GROMACS version:2019.6  
GROMACS modification: Yes/No  
Hi guys,  
I have some questions with the gmx xpm2ps command  
I created a xpm file using gmx do\_dssp , then I converted it to an eps file using the following command:  
gmx xpm2ps -f \*.xpm -o \*.eps -di note.m2p -by 10  
I converted the eps to pdf using convert \*.eps \*.pdf  
Although the tick in the Yaxis show correct output, the tick mark in Xaxis is stacked over each other, which make it pretty hard to observe. The data in Xaxis run from 0 to 50000ps.  
It would be appreciated if you could give me some suggestions to solve this problem.
