The 18th annual CCP4/APS Crystallographic School, "From Data Collection to Structure Refinement and Beyond," will be held from July 7th to 14th, 2026, at the Advanced Photon Source (APS), Argonne National Laboratory (ANL), near Chicago, Illinois, USA. The workshop is co-hosted by CCP4, GMCA and NE-CAT at APS. All details can be found on the school website: http://www.ccp4.ac.uk/schools/APS-2026/index.php. 

Dates: July 7th through 14th, 2026 (on-site), June 22nd, 2026 (virtual)

Location: Advanced Photon Source, Argonne National Laboratory, Argonne (near

Chicago), Illinois, USA 

The school comprises two parts: a data collection workshop and a crystallographic computing workshop. The data collection workshop includes beamline training, data collection at upgraded GMCA and NE-CAT beamlines, and data processing, using only the participants' crystals. The crystallographic computation workshop will feature many modern crystallographic software packages (including CCP4, PHENIX, XDS, HKL, and DIALS) taught by authors and other experts. This workshop will also introduce elements of CryoEM, such as model building and refinement. The daily schedule will be organized in three sections – lectures, tutorials, and hands-on (interactive troubleshooting of the technical difficulties participants face in their projects). An additional virtual day (June 22nd, 2026) will cover sample preparation (cryo-cooling), bioinformatics, and introductory crystallography lectures. We have had considerable success resolving these problems in past years, as attested by resulting publications (see http://www.ccp4.ac.uk/schools/APS-school/publications.php). A draft program can be found on the School website. 

Applicants: The workshop strongly encourages students who need expert help with difficulties/challenges in their own projects. Graduate students, postdoctoral researchers, and early-career faculty, along with commercial/industrial researchers, are encouraged to apply. Only about 25 applicants will be selected for participation. 

Application: The application deadline is May 15th, 2026, but we strongly encourage interested participants to apply as soon as possible. To apply, visit https://www.ccp4.ac.uk/schools/APS-2026/application.php

Fees: There is a $500 participation fee for selected academic students and $1,500 for industrial researchers. No credit card will be required for registration; students who are selected to participate will be contacted to pay. The students will be responsible for their transportation and lodging. The workshop organizers can assist in making lodging reservations at the Argonne Guest House. The workshop will cover all other expenses (including meals).
