Right, I have a pdb where some of the residues are missing and when I try to simulate it I get LINCS warning in between the atom of the two ends of missing residues. So if I use a smaller time step (0.01) for final production run and energy minimization with setting constraint = none, making it computationally more expensive. Will these results will be O.K.
