Dear Gmx Users,

My system is made of 3 proteins. As I want to use distance restraints
dynamics between atoms belonging to each of them I have to produce topoloy
with one moleculetype. I used pdb2gmx -chainsep interactive (I used merge:

Then when I process to grompp the error: "unknown cmap torsion between
atoms  ......."

These atoms belong to the last residue of the chain A and to the first
residue of Chain B. How to get rid of this? Please, help.
