Here post your question ERROR 1 [file topol_1.top, line 121]:
Atoms in the .top are not numbered consecutively from 1 (rather, atomnr =
77, while at->nr = 77)
Program: gmx grompp, version 2019.4
Source file: src/gromacs/gmxpreprocess/toppush.cpp (line 1244)
Fatal error:
There was 1 error in input file(s)
As mentioned in the error, the atoms in .top need to be listed consecutively starting from 1. If you are putting together the protein-complex by combining different files, it’s possible the numbering might not be properly corrected at some step. If you open the .top file with a text editor, you should be able to find where the numbering went wrong (this should be under [atoms], the very first column (nr) should be a consecutive list of numbers from 1)
