Hi Francis, Detwinning of perfectly twinned data is done with reference to Fcalc (determined from from the model): it is not possible to arithmetically deconvolute the contribution of the twin domains to the perfectly twinned reflection data. Because your model is incomplete you will be introduci

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 re
