Optics Group Assignment. Plot of beam shift in × and y for 7,428 movies collected using EPU colored by optics group assignment. Hierarchical clustering is used to group movies based on beam shift, before each group is further divided into sub-populations based on the location identifier in the EPU filename. The user may limit the maximum population of each group and/or apply an offset to the optics group number to aid dataset combination. The data shown were collected using a 1.2/1.3 quantifoil grid with two shots per hole using AFIS beam shift collection in EPU 2.7 (Thermo Fisher Scientific, The Netherlands).
