Hello all,
I believe I have a P41 perfectly twinned as a P41 21 2. I'm using the
detwin_perfect.inp in CNS in every round of refinement to detwin the
original P41 data as I update the single molecule in my asymmetric
unit (so far).
[1] Should I be able to find the second molecule (from reducing the
symmetry from P41 21 2 to P41). Would it be clear as day considering
my first molecule is nearly 90% built? Phaser MR gave two solutions
in P41 when searching for one molecule in the asu. The LLG is nearly
identical. Are these the two twins of my crystal? Should I merge them,
detwin, refine and completely rebuild?
[2] Should I be using NCS constraints?
[3] Would refining with a twin operator on the detwinned P41 data
(using phenix.refine) be helpful?
Thanks!
