1622	Need a method to clear atom's anisotropic B-factors	Tristan Croll	Eric Pettersen	Not to set the entries to zero, but to clear the Atom.aniso_u field entirely and set Atom.has_aniso_u to False. Anisotropic B-factors are some of the most abused parameters in model refinement, and it's often advantageous to wipe them and start over (or switch to using purely isotropic B-factors). At the moment I can fudge the effect I want by setting all the aniso_u terms to NaN (internally, Clipper treats this as the atom having no anisotropic B-factors) - but that leads to garbage ANISOU records being written to the PDB file on saving.	enhancement	closed	major		Core		fixed						all	ChimeraX
