You can click on the red plot marker to display the corresponding image. These lysozyme diffraction patterns have between 15 to 60 peaks.

Indexing

Let's try to index the diffraction pattern at event 11.

• In the experiment parameters panel, set Event Number to 11.

In the indexing panel, tick "Indexing on". Indexed peaks will be marked with magenta circles.

Notice that the unitcell parameters are a bit off for lysozyme. Let's load a CrystFEL unitcell file to help indexing.

• In the indexing panel, set the PDB field to: /reg/d/psdm/cxi/cxi06216/scratch/psocake/lys.cell
