Hi Steven,

There will be three dihedrals spanning a break. Make sure to remove all of
them. Of course pdb2gmx shouldn't just connect the chain ends... Maybe you
can file it as a bug.

Cheers,

Tsjerk

Yes, it works (-chainsep interactive: merge = yes ) but when you process to
grompp there is an error:

Unknown cmap torsion between atoms 6002 6004 6006 6017 6021

pdb2gmx takes the cmap for the atoms e.g. last two residues of chain A with
first three residues of chain B. Removing these lines does not solve the
problem. Any suggestions appreciated!
