[ccp4bb] twinning in monoclinic space group

2008-10-22 Thread Michael Karl Uhl
Hello everyone, I have collected a dataset with a resolution of 1.5 A. The indexing with denzo went very well with the monoclinic cell (62.3120 84.2860 72.8720 90. 111.9620 90.). After many trials to determine the structure with MR as well as SAD I thought that my dataset might

I dont think that is a twinning law, and that SG and cell dimensions are unlikely to be twinned. It could be really P1 I suppose with a twin operator -h,k,-l - ie the SYM op is actually a twin operator.. But twinning usually shows up in the intensity statistic plots - have you looked at the
