I'm interested in doing a bunch of runs with slightly different restraint forces, I have certain queries regarding this:
1) how can I set a force constant and change it according to my need by making changes only in the .MDP file of equilibration?
2) do I have to do this manually all the time by changing the .itp file and replacing all the 1000 (by default) to say 100 etc?
3) if I apply positional restraints by not changing the. Itp but getting my restraints #included in. Topology file, why can't I see the positional restraints as 1000 getting applied in .log file of equilibration?
