Here post your question
Hi everyone i have a gromacs trajectory and i want to create a contact map for some specific aminoacid in a region of my protein. Anyone can tell me how i can do this?
Thanks a lot.
you can have a go with
gmx mindist which tells you if things were in contact or not.
If you’re not afraid of compiling some old code, you can have a try with g_contacts which has an option to give you per-residue contact frequencies (read more here ;) )
I have gromacs 2019.4
I’m trying to use mindist but i don’t understand how to insert the data to do this analysis. Can you tell me if i need to insert an index?
The index is for an especific atom or can be an aminoacid residue?
Thanks for your help.
