I'm having a discussion with a colleague here about what we expect to see on a model with and without TLS being used. I had the expectation that if you'd compared both models the Biso values reported in the ATOM line for the same atom w/ and w/o TLS would be somewhat comparable. Not the same, because the ADP model is different, but similar. However in the case of the TLS-refined model the average B-factors are systematically higher over the whole structure (86 A^2 vs 69A^2 for one polypeptide chain). Is this reasonable ? Expected ?
