Thank you for the info. Now I have upgraded to gromacs 2020.3. Yes the conversion is working. Unfortunately, the graph scales (x- and y-axis) generated are badly overlapping (unreadable) refer attached. ![Screenshot from 2020-07-15 11-54-42](https://europe1.discourse-cdn.com/flex017/uploads/bioexcel1/original/1X/90fabb4fee3ad5d02e9944a648c4ea55d34412d5.png) How can I fix this? your help is much appreciated. thank you. ---

There is a template file for conversion at /path-to-gromacs/share/top/ps.m2p. You can provide template file with **-di** option. Copy that file to current directory and adjust x-major/x-minor and y-major/y-minor, then supply with -di option while invoking **gmx xpm2ps**. ---
