Coarse-Grained Parameter Files - jasonlai - 09-27-2012 08:00 AM

From talking with some of you over the summer, I know that you favor the all-atom model with Medusa and no longer support coarse-grained models.

However, in the past, your group has published papers using various types of coarse-graining using DMD. Even though these files are no longer compatible with the latest version of piDMD, I was wondering if I could see those parameter files anyway. It would be really beneficial as a starting point to building my own CG force field so that I don't have to do the parametrization from scratch.

Thanks

Hi Jason,

The parameters for most of the coarse-grained simulations are recorded in the corresponding papers. I haven't had a time to formalize the parameters for the pDMD package. Based on the tutorial and the parameters in the paper, you can create input files for pDMD simulations.
