[gmx-users] GC and Constraints - What to conclude?

[Alan Wilter Sousa da Silva]

Hi,
	I still have doubts about GC optimisation vs. Constraints (LINCS
etc.).
	I am assuming that is *all true* what it's written in GROMACS
Manual when referring to GMX 3.x.  I would like to know if my 2 conclusions
are right for a system composed of protein plus water molecules in a box:

	(1) Since GC opt. cannot work with Constraints and Freeze groups,
(2) GC opt. over this system can be done but only without any constraints
or fix atoms.

	I have some questions over these points but I'd wait first any
commentary.

Many thanks in advance for any attention.
