Dear gmx users,
I have modified the top file of my input.pdb. In this modification I have
deleted 2 atoms, bonds, and diedrals which these deldeted atoms are involved.
The atom numbers of deleted atoms are 2 and 3.
IN grompp I get a fatal error that the top file has not a consecutive numbers
and doesn't start from 1.
Would it be possible to solve this problem? Am I supposed to renumber the atoms
and other things manually? Is there any command to renumber the top file? Or is
there any other solutions?
You need to renumber the topology, and all interactions are affected. Scripting
is your friend here. There is no Gromacs program or command that will do this,
since modifying topologies in such a way is not normal behavior.
