[gmx-users] rotamers during minimization

[abdullah ahmed]

Hello, 
I would like to know if gromacs is designed to try and keep as close to the original structure as much as possible? After minimizing a structure with phenyl-alanines I realized that a better minimization could be achieved if the rotamer had been changed during the minimization. However I have been unable to induce gromacs to do this on its own during minimization. I could of course, change the original structure but I prefer not to. 
Thank you in advance, Abdullah Ahmed
