[phenixbb] Anisotropic B-factors with Trucated Data

Dear Crystallographers, I have a dataset which was artificially truncated at 1.7 Ang by the limitations of our setup, but the resolution is probably 1.5 Ang or so. I would like to try running anisotropic B refinement in Phenix, but am not sure how to tweak to get this to happen. I know about the parameter:measurement ratio concept, but I think it may still be better than isotropic. NB the dataset is also 42% twinned. All the best, Jacob Keller ******************************************* Jacob Pearson Keller, PhD Looger Lab/HHMI Janelia Research Campus 19700 Helix Dr, Ashburn, VA 20147 email: [email protected] *******************************************
