Hello Gromacs users,
I am running MD for a protein with its crystal water. I have again solvated the system using genbox. Thus the topology file contains 4 groups under the division molecule as
When i go for preprocessing the system for MD, i got an error
Fatal error: atom no.2015 in more than one T-coupling groups (14 and 2)
i checked the gro file to find that atom 2015 corresponds to last atom of the ligand.
I checked the index file. it has no error.
So i have given the index file as an input and rerun the grompp command.
This time i got an error
FATAL error: atom 2469 in more than one T-coupling groups(15 and 2)
and this atom corresponds to the last atom of the SOL (crystal water) group.
I have also checked the index file to find no error in grouping this atom.
Can anyone suggest me how can i get rid of this problem
Thanking you in advance
