Hello

I am working on a macro to measure individual corn kernels placed in a 6x8 tray. I am able to start with a scan of the tray and get measurements for each individual kernel using the "Analyze particles" function, but I'd like an automated way for the ROI Manager to label each kernel (A1, A2, ... , F8), or at least number them in order (label the kernel in A1 as 1, the kernel in A2 as 2, the kernel in F8 as 48), without having to manually relabel them myself.

From observation, it seems like the default for the ROI Manager is to label in order of smallest to greatest y coordinate. If there was some way to change the default to label based on both y and x coordinates, then maybe it would work. However, I am unfamiliar with programming (I have been exclusively using the "Record Macro" function so far), so any suggestions on how to change the labelling or any other ways would be great.

Thanks
