Hi Mark,

I want to refine the model for any bad contact if the structure has. This
article support the simulation of any homology model after its creation by
homology modeling approach "
https://www.ncbi.nlm.nih.gov/pubmed/22513870?dopt=Abstract". Do you please
think that there is no need to refine the model via simulation? or the
claim which i do for refinement via simulation, is biased?

Thanks for consideration!

Amir
