I want to do restrained energy minimization for ensemble of conformers
obtaind from CYANA.
I have tried doing minimization without any NMR constraints , and i
did MD in explicite solvent.
I wanted to know very basics ,
1. when we should do only just minimization,
2. when we should do minimization with NMR constraints
3. When should we do minimization after running MD and also along with
NMR constraints.
regards
