"Two-color intensity along junctions.ijm" is a macro toolset for ImageJ. It was used to extract data for Figures 1 and 2.

It is used to extract the intensity along junctions of two-color images and image sequences. Macros are specific to junctions observed in the apico-basal and planar orientation. "Result" macros generate files consisting in the concatenation of the information of multiple junctions.
