DESCRIPTION:In recent years\, electron diffraction has arisen as an alterna
 tive to X-ray diffraction for structural studies on threedimensional cryst
 als. Promising features of the technique include complete data sets from a
  few or even singlenanocrystals\, sensitivity to the charged state of ions
  and the relatively low expense of the apparatus. Experimentalprotocols an
 d detector technologies are improving\, so that data collection using the 
 rotation method\, dominant inX-ray crystallography\, is now feasible in a 
 cryoTEM. This convergence of experimental techniques has beenaccompanied b
 y repurposing of analysis tools: robust and sophisticated algorithms devel
 oped over decades forX-ray diffraction integration software can be now emp
 loyed to tackle electron diffraction data. Nevertheless\, thegeometry of t
 he electron diffraction experiment incurs specific challenges to address i
 n the analysis. Here\, thediffraction integration package DIALS is discuss
 ed\, highlighting particular adaptations that were made to thesoftware for
  various example cases of electron diffraction\, particularly on protein c
 rystals. The experience gainedindicates that integration of good quality E
 D data can be straightforward\, but the bottleneck remains with collection
 of such good data\, which relies on careful calibration and understanding 
 of the instrument. Improved apparatus willameliorate this issue and future
  studies to develop improved models for details including dynamic diffract
 ion andabsorption are anticipated.\nSpeaker: David G. Waterman
