NX client installation and remote desktop workshop

On Tuesday, there will be a workshop to install and configure the NX client in the participants' laptops, and to learn how to access the data and demos in the practical tutorials.



Orientation to experiments at SSRL

On Tuesday after the afternoon lectures, there will a compulsory orientation to experiments at SSRL, covering safety, at building 120. There will be two talks:

  • 15:30: Safety talk (Last name starting with A-L)

  • 16:00: Safety talk (Last name starting with M-Z)



LCLS Tour

Sign up sheets for the optional tour of the free electron laser facility LCLS will be available on Tuesday. Groups will set off from building 48 (there is a ~15 minute walk to the LCLS). The tour will include a visit to the beamlines CXI and MFX, used for macromolecular femtosecond crystallography. The tour takes about 45 minutes.

Beamline Tutorials

We will offer tutorials for sample preparation, cryo-cooling, mounting and characterization; SAD/MAD data collection; RT data collection; crystal dehydration and UV-Vis spectrophotometry. All the participants will get the chance to learn how to collect data from their own samples or standard samples.

  • Data collection on BL12-1: Irimpan Mathews and Darya Marchany-Rivera
  • Data collection on BL12-2: Clyde Smith and Silvia Russi
  • MAD/SAD data collection on BL14-1: Ailiena Maggiolo
  • Sample preparation and harvesting tips and tricks on BL9-2: Jim Pflugrath, Elspeth Garman and Tzanko Doukov
  • UV-Vis Microspectrophotometer introduction on 9-2: Aina Cohen
  • RT data collection/crystal dehydration: Silvia Russi and Darya Marchany-Rivera

The participants must sign-up in advance for the tutorials they wish to attend. Instructions on how to access the sign-up sheets will be given during the course.



Software Tutorials

Software tutorials will be offered on several different packages for data processing and structure solution, including:

  • Structure solution and refinement with Phenix: Li-Wei Hung, Pavel Afonine, Nigel Moriarty, Oleg Sobolev, Billy Poon and Dorothee Liebschner
  • Data processing and phasing with CCP4: Harry Powell and Andrey Lebedev
