Re: [ccp4bb] To scale or not to scale: XDS_ASCII.HKL input to POINTLESS/AIMLESS

Dear Kay Just to comment on (e) since you say you don't know why anyone would want to do this, yet this is exactly what xia2 -3d does :o) I use AIMLESS to merge data already scaled by XDS CORRECT or XSCALE as a way to get a report on the merging statistics which includes all of the AIMLESS

BLEND is mainly applicable to cases with many more than 3 data sets. So I would say it does notadd anything useful to what already suggested by Matthias. I have had positive results when scaling and merging several (unmerged) anisotropic data togetherwith POINTLESS / AIMLESS. The main reason

Dear Graeme, good that you set this straight. I consider getting the statistics output from AIMLESS is a perfectly valid reason for going e), and as long as this is well-tested (which I'd bet in case of xia2) it's ok. There is one issue I can see: 99% (obviously my guess could be wrong; just

Dear Kay I cannot comment on the accuracy or otherwise of your 99%, but every time I talk about xia2 or write down what the options do, I try to make it clear that XDS / XSCALE is used for integration scaling then AIMLESS to merge the data. I have had an interest for a while in scaling the data

Dear Robert, the data sets don't seem too anisotropic, and the week reflections in poorly reflecting direction of dataset 1 that you include by setting the resolution range to 3.5A may not deteriorate the overall scaling that much. They may actually be kicked out as outliers and not used for

Hi It's possible (though Garib has told me you shouldn't do it...) to integrate using anisotropic limits with Mosflm - it's pretty straightforward. Some users have told me it really helped. On 12 Nov 2014, at 21:26, Robert Keenan wrote: I have three datasets of varying quality collected
