Hi,

I came across some errors when running MMPBSA.MPI. Following is the output:

---------------------------------------------------------------------------------------------------------------------------------------------------------------------

I have AmberTool 1.5 with Amber 11 fully patched and compiled with gnu compiler. Mpi4py is built with openmpi-1.4.3.

Any idea what's going wrong?

Thanks
Ye
