Hi all!!!
I am trying to run a MD simulation with part of my system frozen. I was looking into the manual but I couldn't find the answer since the manual says the way for freezing complete groups. I would like to freeze only a part of my protein and permit the completed optimization of the rest. For example, my protein group has 5 protein chains with 42 residues each of them. I would like to freeze (in all directions) the alfa Carbon atoms for residues 18-42 for each chain. Does somebody know if it is possible to do such thing with GROMACS? Can somebody help me?
Thanks a lot, in advance
Marcelo
