XSCALE
<http://www.mpimf-heidelberg.mpg.de/%7Ekabsch/xds/html_doc/xscale_parameters.html>
is the scaling program of the XDS suite. It scales reflection files
(typically called XDS_ASCII.HKL) produced by XDS. Since the CORRECT step
of XDS already scales an individual dataset, XSCALE is only /needed/ if
several datasets should be scaled relative to another. However, it does
not deterioriate a dataset if it is "scaled again" in XSCALE, since the
supporting points of the scalefactors are at the same positions in
detector and batch space. The advantage of using XSCALE for a single
dataset is that the user can specify the limits of the resolution shells.

Thank you Boaz.
So if CORRECT can do a fully corrected scaling, are there no
corrections that XSCALE might apply to XDS_ASCII.HKL data that are
beyond CORRECT's capabilities?

Hi,
I actually choose the option 'constant' further down in the
aimless gui but I guess the effect is similar to 'onlymege'.

to POINTLESS/AIMLESS
Hello all,
in a discussion
<https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind1307&L=CCP4BB&H=1&P=186901>
on this board, Kay Diederichs questioned the effect of scaling
data in AIMLESS after prior scaling in XDS (CORRECT). I understand
that the available alternatives in this work flow are to specify
the AIMLESS ‘onlymerge’ command, or not.
Are there any arguments for the preference of one alternative over
the other?
Thank you for your insights,
Wolfram Tempel
