Dear Crystallographers I am trying to print out my total B factors using TLSANL (version: 6.1) in CCP4- 6.1.1. My TLSANL’s input file.pdb is coming from refmac (version: 5.5.0072) using the TLS & restraint refinement option and isotropic B factors. The TLSANL’s output file.pdb contains the following ATOM and ANISOU records as an example. REMARK 3 TLS DETAILS REMARK 3 NUMBER OF TLS GROUPS : 2 REMARK 3 ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS REMARK 3 ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS ATOM 88 C ASN A 14 0.748 -5.841 -6.258 1.00 35.84 C ANISOU 88 C ASN A 14 5335 4549 3734 0 0 0 C ATOM 89 O ASN A 14 0.807 -6.941 -6.845 1.00 35.04 O ANISOU 89 O ASN A 14 5229 4375 3709 0 0 0 O I am not able to understand why my ANISOU record contains ‘0 0 0’ for the anisotropic component. Something is not correct and I'm not sure why I am not able to print out my total B factors. I would appreciate it if someone could tell me what is going wrong and how can I print my total B factors. Thanks Regards Shiva Kumar
