It seems that the amoeba.prm file has torsion parameters (I think with zero
force constant) that connect atoms not connected by bonds. The data
structures in sleap don't permit this. You could try to see how many of these
torsions there are, and try deleting them. Or, you could copy the ion
parameters into amoebapro.prm.
