A couple of extra comments on top of Bob's rather comprehensive recommendations, based purely on actually looking at Pilatus data (I mean *looking*) When you are inspecting the images looking at them at 100% size is important: spots are small relative to pixels and the point spread is essentially

The seminal paper on actually how to collect data from detectors like this and others with negligible read-out time is this one, which I strongly recommend: Optimal Fine phi-slicing for Single-Photon-Counting Pixel Detectors Marcus Mueller, Meitian Wang, and Clemens Schulze-Briese, Acta Cryst.

Hi Theresa, one issue I noticed during -admittedly few- collections on PILATUS detectors, are low symmetry space groups and perfectly centered detectors. The many seams of the detector left us with <90% complete triclinic data sets. A slightly imperfect centering of the detector or collections a

Dear crystallographers Is there a good source/review/software to obtain tips for good data collection strategy using PILATUS detectors at synchrotron? Do we need to collect sweeps of high and low resolution data separately? For anomalous phasing (MAD), does the order of wavelengths used affect
