There is a difference in visualising Saturn detector images in MOSFLM and how they are handled in XDS (and also inside autoPROC): adding the argument
% process XdsToMosflmExtraArg="-r1" ...
should fix that and one should be able to visualise predictions with e.g.
% ipmosflm < 01/view.dat
Note: the better option is to use our own GPX2 visualiser (as of releases from June 2015 onward).
