It is often the case at the beginning of a beamtime that the detector distance to the interaction point (coffset) is not well known, and we can use the diffraction geometry panel to find this distance.
- In the diffraction geometry panel, set "Detector distance" to 156mm. Try incrementing this distance in 1mm step till the unit cell parameters are as close as possible to lys.cell. The optimum detector distance is around 158mm.
- Try drawing a resolution ring on top of the water ring by using “Resolution (pixels)” field. If your detector distance is correct, the crystallographic resolution ring should display 3.4A.
Future plans
- More mask shapes
- More integration with logbook
- Extend the crystallography analysis to XPP and MFX beamlines
- cctbx-xfel support
