Ok first of all, DOH! I always forget I can do that in google. But as Pavel suggests I put in my questions anyway, here it goes....
From the Yeates twinning server and xtriage my data seems to be twinned at approx 22-25%, the log is attached. I have an MR solution from a related MAD structure I solved and Arp/Warp rebuilt 99% of this structure without any account for twinning. Upon refinement with twinning I get what I think are overly good (refined) R/Rf values (particularily with waters = refine 3). And refinement without twining gives R/Rf on the bad side for my resolution (2A) but not so terrible. And these improve to "reasonable" R/Rf with the inclusion of TLS and waters (= refine 5). I have looked at the structures and maps for both refine3-twin and refine5-notwin and see little differences but nothing major. So my dilemma is which structure to continue refiniing the twinned or not twinned+TLS, how do I know which is correct? My other questions alternate conformations, is it possible to refine the occupancy?

Google seems to be indexing it.

Hi phenix community Is there a search function for this bb, as there is for the ccp4bb? I have some questions about twinning, TLS and alternate conformations in phenix.refine. I hate repeating questions that have been answered previously but going thru the Archives month by month is proving to be a little slow.
