Hi, Thanks for the response!
What I have are crystal structures of the same protein in multiple conformations, solved by different groups. I wanted to calculate the residue-wise B-factors for each of these structures and compare how the values are changing for corresponding residues in these different structures. e.g. B-factor variation in residue number 200 (Ala) in 10 different conformations of a protein. Hope I have been able to answer the question!
