DIRECT-ID

Given below are various scripts, software packages and data that we have developed and are making publicly available. For anything related to force field development, please see our Force Field Development page.

DIRECT-ID

The DIRECT-ID method computes norm difference matrices from covariance matrices routinely computed after MD simulations. The norm surfaces can be used to (1) quantify the extent of difference in the dynamics and (2) extract structurally relevant features that contribute most prominently to the dynamics. These differences can be a function of solution conditions, ligand binding, etc.
