Cell-o-Tape 

Cell-o-Tape is a Fiji macro to count and measure individual neighbouring cells along a defined file in confocal laser scanning microscope images.

The tool allows the user to extract this information, and builds on the raw data to detect a significant change in cell length along the file. This facility can be used, for example, to provide an estimate of the position of transition into the elongation zone of an Arabidopsis root, traditionally a location sensitive to the subjectivity of the experimenter.
