Sebastiano, CORRECT does scale the data. XSCALE is only needed for two or more datasets, or if other requirements exist - you named one. The two varieties of FRIEDEL'S_LAW differ in their rejections! HTH, Kay Sebastiano Pasqualato schrieb: > >Thanks to Kay and Tim or the feedback. > >The

The XDS CORRECT step will also (by default) do scaling - if I understand correctly the same scaling as in XSCALE, but for a single sweep and with no zero-dose. If what you want is merging statistics, I find it helpful to write out the data unmerged and then use pointless -c and aimless to merge th

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear Sebastiano, if the output of GO.COM produces an mtz-file you can use for phasing or refinement, I am very confident there is a scaling step involved. This might also be an explanation for the discrepancy you point out: With FRIEDEL'S_LAW=TRUE the

Thanks to Kay and Tim or the feedback. The reason I wanted to get statistics from the CORRECT step of XDS is that I have refined a structure using the mtz output by the GO.COM automatic reduction routine of SLS beamline PXIII, which does not involve a scaling step (I discovered recently). I wa

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear Sebastiano, you could use xprep to get the statistics in user defined resolution shells. Out of curiosity: Would you mind sharing why you want to do this and why you don't want to use the XSCALE statistics instead? The statistics are probably mo

Dear Sebastiano, sorry, it is not possible. Indeed, only XCSALE allows you to define the resolution ranges yourself. HTH, Kay On Tue, 15 Jan 2013 16:22:14 +0100, Sebastiano Pasqualato wrote: > >Hi all, >I was wondering if XDS allows to change the number of resolution bins >appearing in the

Hi all, I was wondering if XDS allows to change the number of resolution bins appearing in the table: SUBSET OF INTENSITY DATA WITH SIGNAL/NOISE >= -3.0 AS FUNCTION OF RESOLUTION of CORRECT.LP. Please, note that I am not referring to the table output by XSCALE, in which you can change the res
