Dear All, Thank you very much for valuable suggestions and educating me on the normal mode refinement. Actually, I am trying to refine a protein (cytosolic domain and trans-membrane domain). I found a solution through PHASER and density looks really good in both domain but as i proceeds with

I agree with Ethan. In philosophy, NMA is a useful analysis to study low frequency collective motions. That is true by taking a stand-alone structure and explore such motions of biological interest. Domain motions in the crystallographic environment need not necessarily correspond to those

Hello, You can also contact elNemo or NOMAD-Ref server developers about getting covariance/correlation matrices from normal mode analysis outputs to know the correctly coordinated mobile atoms. In this way you can compare with biological data also. In Shekhar's said paper K. Suhre (one of the
