This even seems to have a”batch” mode (similar to the well-known homology modelling server Phyre2) that might accept a zip file containing multiple PDBs. If it does, and if it will take my ~700 PDBs, then that would save me a little bit of scripting. Harry > On 27 May 2021, at 22:03, Jon

A bit late, I know, but a bit more googling gave me this site which I don't think has been mentioned so far: http://old.protein.bio.unipd.it/mobi/ Given the pdb code, it is a one click job to get a pdb file with the "B-factors changed to averaged Scaled Distance x 100" and the resulting

If you want something comparable to B-factors don’t forget to put the MSF in the B-factor column, not the RMSF. Will change the scaling of the tube radius considerably! Nick On 27 May 2021, at 11:16, Harry Powell - CCP4BB

Hello, In my understanding of NMR, the loops and terminii that adopt very different conformations in the structure ensemble rather reflect the fact that for those residues, the number of constraints is lower, thus the number of structures that fulfil the constraints is larger A dynamics
