Dear all,
I have refined a 2.5 A structure (P212121, a=29, b=56, c=58) with
Refmac/TLS to an R/Rfree of 20.9/23.7. Everything seems to run
smoothly, maps look nice. Total B-facors for protein (residual+TLS)
after TLSANL are in the 25 to 50 A^2 range.
However, water B-factors are refined to unreasonably low values, many
hitting bottom at 2.0 A^2.
A refmac refinement without TLS easily fixes the water B-factors to
reasonable values, but gives 2-3% higher R-factors. (I have attached
the relavant parts of the PDB file from TLSANL)
Thanks for your help.
Clemens
