Just a few simple thoughts:
--1) Are you certain about the space group, and did you try letting
--Phaser pick one for you? (It sounds like you did, but I can't tell
--from your description.)
I searched for a solution in all possible space groups in P 4. I
thought I was certain of the space group, but maybe not...
--2) How much refinement did you run to get an R-free of 42$, and did
--you already try running AutoBuild with rebuild-in-place turned off?
--Refinement alone may not have the radius of convergence you need.
True, I only did a couple of rounds of rebuild/refine
--3) What is the sequence identity?
My model is a point-mutant of the crystal.
--4) Are you using the latest version of Phenix? Phaser has had TNCS
--support for almost a year now but I keep hearing from people who are
--using ancient versions...
I am using the latest official PHENIX built.
