Hi folks, I saw this twin information in the output from PHASER. Please could someone explain to me what exactly this means? What is the actual twin fraction for this dataset? Many thanks, Ray Brown tNCS/Twin Detection Table ------------------------- No NCS translation vector -Second Moments- --P-values-- Centric Acentric untwinned twin frac <5% Theoretical for untwinned 3.00 2.00 Theoretical for perfect twin 2.00 1.50 Initial (data as input) 2.30 1.89+/-0.082 0.08 0.404 After Anisotropy Correction 2.31 1.88+/-0.081 0.0707 0.381 Resolution for Twin Analysis (85% I/SIGI > 3): 3.62A (HiRes=2.81A)
