Re: [ccp4bb] refmac,tlsanl vs TLS, B and anisou

I agree with Paul and George that it is vital that PDB files from TLS refinement contain ANISOUs which reflect the results of that refinement, and would like to reinforce Paul's point below. There are many possible parameter-frugal approximations to full ADP-refinement: TLS is just one of

Dear [EMAIL PROTECTED], I have to correct my earlier statement in an previous email to the bulletin board (see below): One of the detection channels of the AB StepOne is in the right detection range and the signal is strong! Our lab just purchased the new AB StepOne RT-PCR machine for

We do have to mess with the PDB format every time something new is invented. Usually it's just REMARK 3 that has to be changed, but you always need to put some kind of remark in the header that you used a certain type of refinement. When different types of anisotropic refinement are combined

In the end, we're solving all these structures because we believe (or at least hope) that they'll be useful for understanding biology. That means that biologists should be able to understand what we deposit. When I've tried to teach undergraduates what to make of structural models, I find I

I am not mistaken what went wrong in my case is that in resolve.mtz there are the columns FP and SIGFP which are not the experimental F anymore but they are modified ones (solvent flattened, ncs etc...). Clearly refmac5 uses them as Fo for refinement, refining Fc against Fc (an extreme case of

True enough. My comment was in the context of whether it is better to deposit ANISOU lines as a representation of the anisotropy. The default for BRES in TLSANL is indeed false. This was originally done so as not to break the pre-existing RESTRAIN usage. This is taken care of in the GUI, and for
