[gmx-users] EnMin & constraints: Hamletic doubt

Dear GMX community,
I am running simulations of a solvated protein on a (frozen) Au substrate,
but I think that my question is so basic that it falls outside the details
of my case...
So, the question is: when I prepare the system by minimizing the energy,
should I set constraints = all_bonds, h_bonds or none?
IMHP, I should set it to all_bonds, otherwise I may risk that the system's
energy minimum corresponds to a configuration very different from the
initial one... However, I saw somebody is using constraints = none and I
was wandering why...
Would somebody take the pleasure to embark on the discussion of such an
issue with me? Thnx in advance,
