Hello all,

Thanks to Holger and everyone who responded to my last message on the
subject.

I have been trying to implement mm_pbsa and I've come up against a
couple of errors that I
can't seem to overcome. (As an aside, I have a code fix if anyone wants
to use this module with the glycam paramaters for carbohydrates)

My system consists of a protein receptor with 2019 atoms, and a
carbohydrate ligand of 51 atoms (and water).

Using the GC option to get snapshots:

I get the error: broken pipe

and a log file like this:

 Something wrong with NGR 2020 2019

I've tried using snapshots from a Carnal coordinate strip of the same
trajectory, but I get nothing but empty all.out files.

Any help is appreciated...
