[gmx-developers] helix constraint

[Lakshmi Padmavathi]

Dear gromacs users,

                i would like to do MD simulations of a protein which is 
unfolded manually. when i do the MD simulations the secondary structure 
(HELIX) should be constrained. only helices should constrained or restrained,
how can i do it?

is it possible to make this in gromacs? I hope some one of you could help me.

thank you very much.

sincerely,
