Dataset for measuring tendency of Y-junctions to line up into grain boundaries during incorporation into retinae

This dataset contains images of UV cone nuclei near the retinal margin in live fish. These UV cones express a transgenic fluorescent reporter (that is nuclear-localized and photoconvertible).

The most important images in this dataset are:
Zoomed-out (1X magnification) images immediately after photoconversion
Zoomed-out (1X magnification) images two to four days after photoconversion

In the images immediately after photoconversion, we check if the row orientation rotates by more than a certain amount (10 degrees, 12 degrees, 14 degrees, etc.) at the retinal margin. If so, we call the region coinciding with this domain rotation an existing grain boundary. We, then, check where new Y-junctions are incorporated (by the time of later imaging) to see if they are preferentially incorporated near existing grain boundaries.
