measurments within a (moveable) grid

spt
Hello,

I would like to create a grid (for example, 500um wide and 300um high, with 50um squares) that I can then position at a desired location to be able to make measurement within the individual squares of the grid-I can envision how to do this using ROI's but not how to automate it...
Does anyone have any suggestions?

Thanks very much

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
