In case anyone else comes across this looking for a solution, here is what worked for me.
I’m new to Gromacs, but I ran into a similar issue. I resolved it by removed the first “/” in the include statement.
ie. Having the line
#include “/toppar/martini_v2.2.itp”
in my .top file resulted in the same fatal error you described, and this was fixed by replacing this include statement with
#include “toppar/martini_v2.2.itp”
It seems like the file path in your include statement began with “/” as well. Your fatal error shows the file path as “/home/…”.
