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
