Hi Jan

this is probably the same feature in Saturn headers that's upset the
xdl_view display of very strong pixels in ipmosflm (though it doesn't
affect iMosflm, and doesn't actually affect processing).

RAXIS_COMPRESSION_RATIO was set to (I think) 32 in older Saturns, but
this value is not part of the standard used by Rigaku - in principle,
it can be any value, and any software that expects it to be a
particular value may well end up with problems. Newer Saturns
certainly have RAXIS_COMPRESSION_RATIO set to 128 in at least some of
the images I've seen.

So if XDS doesn't expect 128, and it bombs out as a result of it,
this is probably one for Kay or Wolfgang to fix! (I say this not
knowing much about running XDS - there may be a command-line way to
get round the problem)

I really hesitate to say this, but if you want to get started
processing quickly you'll have to use alternative software (Mosflm,
d*Trek come to mind straight away, although I understand there's
another program that's quite popular - its name escapes me ;-)).
