A one-day Appion Workshop was held on Tuesday, June 14, 2016 from 10:00AM to 4:00PM. The Appion Part 1 Workshop provides hands-on training for the Appion single-particle data processing workflow. Appion is a “pipeline” for processing and analysis of EM images; it is integrated with Leginon data acquisition, but can also be used stand-alone after uploading images or particle stacks. Topics include analyzing the quality of your data collection, correcting the CTF, generating and cleaning up stacks, and generating 2D class averages. If you are interested in attending an Appion Part 1 Workshop, please register here. The workshop is limited to 10 attendees.
