Hi,

I am parametrising a zinc atom for a metallo enzyme which structure
contains 98 water molecule. I noticed that MCPB allows only some
molecules of water to be carry hydrogen while for others it gave the
following error:

'1 Error in watProtonate ... exiting
terminate called after throwing an instance of 'MTKpp::MTKException'
Aborted'

for example for (copying from my n ame_fixed.pdb file):
HETATM 3384 O HOH A1075 22.292 89.675 122.382 1.00 14.94 O

$ MCPB -i name_addHs.bcl -l name_addHs.bcl.log : runs
successfully
while for
HETATM 3385 O HOH A1076 22.554 100.265 124.873 1.00 17.05 O

MCPB returns

1 Error in watProtonate ... exiting

terminate called after throwing an instance of 'MTKpp::MTKException'
Aborted

Does anybody have an idea about how to solve this problem ?

Thanks
