A complete description of how to process serial crystallography data with XDS/XSCALE is given in [[SSX]]. A program that implements the method of [https://doi.org/10.1107/S1399004713025431 Brehm and Diederichs (2014)] and theory of [https://doi.org/10.1107/S2059798317000699 Diederichs (2017)] is [[xscale_isocluster]].

== Preparing a reference data set ==
If the refinement was done with phenix.refine, one could use
<pre>
mtz2various hklin 2bn3_refine_001.mtz hklout temp.hkl <<eof
OUTPUT USER *
LABIN FC=F-model PHIC=PHIF-model
END
eof
</pre>
- the column corresponding to PHIC will not be used by xdscc12. Alternatively,
<pre>
sftools
read mymodel_001.mtz
write temp.hkl format(3i5,f10.3) col F-model
y
quit
</pre>
== Anomalous Fcalc as reference (under development) ==
The easiest way is to run phenix.refine with options (in case of S as anomalous scatterer)
refinement.input.xray_data.labels="F(+),SIGF(+),F(-),SIGF(-),merged"
refinement.refine.anomalous_scatterers.group.selection="element S"
strategy=individual_sites+individual_adp+group_anomalous+occupancies
and then
<pre>
sftools
read mymodel_001.mtz
write temp.hkl format(3i5,2f10.3) col "F-model(+)" "F-model(-)"
y
quit
</pre>
sftools seems to output only the acentric reflections - but that should be ok since only those have anomalous differences.
