[gmx-developers] MC with GROMACS

[René Pool]

Nice work André!
What version of gromacs are you working with? (if I remmeber correctly, 
it was 3.something).
I'd be happy to make the GCMC module compatible with that version as 
well as make it compatible for the latest version of gmx. Keep in mind 
that for now it only works for the LJ system, but it's the first step 
towards GCMC with 'real' molecules.

I agree with Michael that it would be a good idea to have a separate 
discussion group for more specialized stuff. I have no idea how many 
people are interested in gmx-mc? If the interest is too low, a separate 
discussion group could be overkill.

Cheers,
René
