TWINNING: TWIN LAW=-H,-K,L, TWIN FRACTION: 0.502. 2. Structure has been refined using PHENIX.REFINE, PHENIX.XTRIAGE programs. 3. When refining TLS, the output PDB file always has the ANISOU records for the atoms involved in TLS groups. The anisotropic B-factor in ANISOU records is the total B-factor (B_tls + B_individual). The isotropic equivalent B-factor in ATOM records is the mean of the trace of the ANISOU matrix divided by 10000 and multiplied by 8*pi^2 and represents the isotropic equivalent of the total B-factor (B_tls + B_individual). To obtain the individual B-factors, one needs to compute the TLS component (B_tls) using the TLS records in the PDB file header and then subtract it from the total B-factors (on the ANISOU records).
