Here post your question Hello gromacs users, is there a simple way to make gmx hbond output a contact matrix for every n frames that can then be viewed as a movie? ie my trajectory has 1000 frames, I want to know how the h bonding or van der waals contact patter nchanges over the course of the trajectory so I want 100 contact maps containing the H bonds in each consecutive ten frame blocks?

You can make contact map for each frame as image file, then from image files make movie using tools such ImageMagick, ffmpeg.

HI Masrul, I would recommend ConAn if yo uwant to do anythign similar. I had found it before but I hadn’t bee nable to use it easily because of an IT issue now resolved. thanks for your suggestion though I will remember it for occasional quick use
