I am pleased to announce the immediate availability of the latest CHARMM36 force 
field in GROMACS format.  You can obtain the archive from our lab's website at 

The present version contains up-to-date parameters for proteins, nucleic acids, 
lipids, some carbohydrates, CGenFF version 2b7, and a variety of of other small 
molecules.  Please refer to forcefield.doc, which contains a list of citations 
that describe the parameters, as well as the CHARMM force field files that were 
used to generate the distribution.

We have validated the parameters by comparing energies of a wide variety of 
molecules within CHARMM and GROMACS and have found excellent agreement between 
the two.  If anyone has any issues or questions, please feel free to post them 
to this list or directly to me at the email address below.

Happy simulating!
