Dear everybody,
I need to simulate a protein with two manganese ions,I have import the
MN2+ parameters that download from
www.pharmacy.manchester.ac.uk/bryce/amber.Because in my situation the Mn2+
is coordinated both to amino acid both to ligand,so I bond these atoms each
other.
I run desc complex.311.MN/complex.312.MN,the bond looks added now.
----------------------------------------------------------

But when I runed 'saveamberparm complex ca-pp2a.prmtop ca-pp2a.inpcrd',I got
serveral errors below,I thought that the metals.prp is not include the bond
information,could you give me some advises,I need your help very much.
