Hi Erik,

What was the issuse you metion with the BSC0 parameters (I take it you 
are referring to the contributed force field that I added to the GROMACS 
website)? I tested the conversion of the new dihedrals by looking at 
single-point energies between AMBER and GROMACS and they matched up. If 
there is a problem, I would like to know so as to be able to take a look 
at it.

Cheers

Tom
