After performing md simulation I want to see the atomic contacts between residues. For that I have performed gmx mdmat and followed by gmx xpm2ps by using following commands
gmx mdmat -f analysis.xtc -s analysis_npt.pdb -mean mdmat.xpm -b 80000 -t 2.5
gmx xpm2ps -f mdmat.xpm -o mdmat.eps -rainbow blue -bx 10 -by 10
But I am getting some unexpected output. Actually residue numbers are missing there. I am attaching the output mdmat.eps file hope you can understand the problems of the output file. Please help me to solve such a problem.
