Good day Susan,

I'd suggest that you perform the analyses/measurements sequentially,
i.e. for one square region after the other. For this purpose you move a
square-sized ROI of proper size over your image.

For this ROI-shifts you have to write an ImageJ-macro with loops that
gives you the ROI positions. A square-sized ROI is created by the command

        makeRectangle(x, y, width, height);

Although it is possible to use scaled co-ordinates (um) I recommend to
use pixels.

Please consult the commented list of available macro functions at

<https://imagej.nih.gov/ij/developer/macro/functions.html>

and the introduction to macro-coding at

<https://imagej.nih.gov/ij/developer/macro/macros.html>

Good luck

Herbie
