Dear JiYuan,

Please find attached an updated 3H68_OH_mcpb.pdb file with the metal center correctly found.

In $AMBERHOME/AmberTools/src/mtkpp/src/molecule/collection.cpp

changing the lines (around line 230):
metalDonorDists["Zn:SER"] = 1.14;
and
metalDonorDists["Zn:S"] = 1.14;

to
metalDonorDists["Zn:SER"] = 2.14;
and
metalDonorDists["Zn:S"] = 2.14;

fixes the problem. You can do the same and recompile.

This may appear strange but when a ligand oxygen is bound to a metal I use the Serine-metal distance as a reference.
The 2.14A number was problematic in other systems. I will implement a system to allow these parameters to be changed from a file.

HTH,
Martin
