Dear Colleagues, This is a reminder for the upcoming CCP4/APS school. The deadline for registering is coming up soon, please register if you plan to attend. Thanks. Charles, Garib and Qingping ====original announcement ==== Dear Colleagues, We are pleased to announce the *11th annual CCP4 crystallographic school *“From data collection to structure refinement and beyond” will be held on June 18-25, 2018 at Advanced Photon Source (APS), Argonne National Laboratory (ANL), near Chicago, Illinois, USA. All details can be found at http://www.ccp4.ac.uk/schools/APS-2018/index.php. *Dates*: June 18 through 25, 2018 *Location*: Advanced Photon Source, Argonne National Laboratory, Argonne (Near Chicago), Illinois, USA The school comprises two parts: *data collection workshop* and *crystallographic computing workshop*. Data collection workshop includes beamline training, data collection on GM/CA@APS beamlines 23ID-D and 23ID-B equipped with Pilatus3 6M and Eiger 16M detectors respectively, and data processing. For data collection, only the participants' crystals will be used. Crystallographic computation workshop will feature many modern crystallographic software packages taught by authors and other experts. The daily schedule will be organized in three sections – lectures, tutorials, and hands-on (interactive trouble-shooting of the technical difficulties the participants face in their projects). We have had considerable success resolving these problems in past years, attested by resulting publications (see http://www.ccp4.ac.uk/schools/APS-school/publications.php). *Applicants*: Graduate students, postdoctoral researchers and young scientists at the assistant professor level, along with commercial/industrial researchers are encouraged to apply. Only 20 applicants will be selected for participation. Participants of the workshop are strongly encouraged to bring their own problem data sets or crystals so the problems can be addressed during data collection and/or computation workshops. *Application*: Application deadline is *Wednesday May 2nd, 2018*. The application form, the program, contact info and other details can be found at http://www.ccp4.ac.uk/schools/APS-2018/index.php *Registration fees*: The registration for application is free but there is $500 participation fee for the selected academic students and $950 for the industrial researchers. The link for the on-line payments and instructions will be provided once the selection process is completed. The students will be responsible for their transportation and lodging. The workshop organizers can assist in making the lodging reservations at the Argonne Guest House. The workshop will cover all other expenses (including meals). We hope to see you at the school. Charles, Garib and Qingping
