I am trying to run a the second step of MCPB.py but am encountering a
ValueError when trying to generate an frcmod file using the seminario
method.MCPB.py does not seem to convert the 'Force' string to a float. MCPB
produces an incomplete frcmod file that is missing angle, bond, and
dihedral parameters for the Copper. The necessary gaussian files did not
seem to have any problems.

Running Run.pymsmt produces all passing tests with the exception of a few
possible failures on resp calculations.

 The whole error message is listed below. My input is...

MCPB.py -i TS3.in -s 2s

and the output/error message is...

* *
*===================Generate the Initial frcmod file=============*
