[ ccp4 6.1.13 ] [ gui 2.0.6 ] if a data set with merged Bijvoet pairs and a free set is then "made anomalous" - i.e. re-scaled with separated Bijvoet pairs - i do not understand how acentric reflections in the free set are extended by cad or freerflag or uniqueify.
the easy question : is [uniqueify with extension] ->[cad with combination but not extension] adequate? i.e. i gather that cad preserves FreeR records between two resolution limits (e.g. 500-3.5) and only extends them in the higher resolution segment (e.g. 3.5 - 2.1). so do i have this right : for acentrics, -h-k-l will be preserved while hkl go to the work set. That will decrease the fraction of reflections in the Free set by half the number of acentrics in the merged free set, because they would be in the work set. centrics do not meet this problem. -bryan
