Hi Monika, in June we had a summer school at MaxIV, and one of the topics was serial crystallography - with lectures and tutorials. Maybe you can talk to the people who attended the course, and the organizers, Ana Gonzalez and Thomas Ursby, and ask them for help.
It is more difficult to determine the spacegroup in serial crystallography, compared to conventional crystallography. This is because there are several spacegroups that have an indexing ambiguity (non-equivalent ways to index a given diffraction pattern), e.g. P3, P4, P6, P321, ..., altogether 38 out of the 65 Sohncke groups . So just merging the data blindly may give you "computationally twinned" data. Take a look at doi:10.1107/S1399004713025431 . If you use XDS/XSCALE, you can analyze the scaled but unmerged data with xscale_isocluster . If you use DIALS, you could use dials.cosym for this purpose.
