Hi all,
I'm trying to run a simulation of a phenol in chloroform with the oplsaa
forcefield.
I've downloaded the chloroform box from gromacs and added the files to the top
folder.
Everything is fine till I run grompp which says:
Fatal error:
Invalid order for directive atomtypes, file
""/usr/local/gromacs/share/gromacs/top/chcl3.itp"", line 1
After downloading the chcl3 box should i have to modify something else?
I've checked in the manual but I'm not able to understand what i'm doing wrong.
This is the top file of my phenol I get after running pdb2gmx:
;
