Bio-Rad EXQuest Spot Cutter - Manual (Page 310)

Integrated Excision Tool

Note: You always have the option of manually correcting spot positions.
Auto-alignment is not always correct and the manual collection allows you to
readjust your spot positions.
Flag the spot you want to correct in the cutter camera image and drag the spot to the
correct position. Red indicates the spot is below the confidence threshold, green spots
indicate the spot is above the confidence threshold, and the spot becomes white while
it is dragged.
You also have the option of returning to Data Box Positioning.
