Is there a way to constraint bonds of a part of the system while keeping

would like to constraint the bonds of one and would like to keep the other
flexible.

I would prefer to use LINCS to constraint the system


Set the constraints explicitly in the topology of one protein using a [constraints] directive. Then set "constraints = none" in the .mdp file. The constraints read from the topology will override the .mdp setting while leaving all other bonds unconstrained.
