Oops. My link & terminology were a little wayward... I knew what I meant, but the incorrect link may have proven misleading. But the answer essentially remains the same: 1) Integrate everything in MOSFLM 2) Enforce consistent indexing using POINTLESS (unless I am mistaken, there are alternat

Surely the original poster meant "alternate indexing possibilites" (as discussed in http://www.ccp4.ac.uk/dist/html/reindexing.html; for his space group there are indeed 2 ways to index), not "alternate origins". Kay Meyer, Peter schrieb: Doubtlessly I'm confused, but my understanding was tha

Doubtlessly I'm confused, but my understanding was that alternative origins would only be an issue once a dataset was phased (so that wouldn't cause problem during integrating/scaling). I'd thought that using a consistent unit cell during indexing and scaling was a separate issue. Any chance y

Hello Yadong, This is what I would do in your position. 1) Integrate everything in MOSFLM 2) Enforce consistent indexing using POINTLESS (unless I am mistaken, there are alternative origin(s) in p321) http://www.ccp4.ac.uk/dist/html/alternate_origins.html ftp://ftp.ccp4.ac.uk/ccp4/6.0.2/prereleas

Hi there, I have 3 incomplete data sets, collected from 3 single crystals, each accounts for ~40% completeness. They have same resolution range, and randomly overlap with each other a small portion. Mosflm and Scala work well for all 3 separately. The 2 from same beamline have very close stati
