  If you can send me a gzipped copy of the pbeq file you computed, I may
be able to figure out what's going wrong with reading it. I'm guessing
that you used a 64-bit charmm build and that charmm is outputting different
data when compiled for 64-bit mode than when compiled for 32-bit mode.
Any comments you may have about how charmm was compiled would be helpful.
