I’m using the Allen Institute’s mouse ISH data for a project and I wanted to ask about the numbering of individual sections within an experiment. If I take the coronal section dataset for MBP RNA ISH, I notice the experiment ID is 112202838 whereas there are individual coronal sections labelled 112202923, 112202925, 112202927 and so on. Do the last three digits have any significance (i.e., are they the distance in microns of that slice relative to a specific anatomical landmark)? Figured I’d ask how these data were numbered and whether there’s any significant convention to the numbering system used there. Thanks for the help.
