Dear users,
I have used grompp command for minimising my protein and ligand in membrane
after using inflategro command.
My system has no problem in visualizing in VMD. The protein is in proper
order
But I am getting the error

Program grompp, VERSION 4.0.5
Source code file: confio.c, line: 728

Fatal error:
Invalid line in system_inf.gro for atom 6835:

Kindly make some light on this.


The second line in a .gro file specifies how many atoms there are. You've specified too many, since grompp is looking for atom 6835, but it finds box vectors instead.
