I’ve been running the ‘QPCA Pattern Analysis ROI’ on RNL clustered images with two ROIs selected (a gecko’s dorsal area, and the same shape over a representative sample of its background). Some images run successfully, but many produce two JavaScript exception windows instead. Occasionally the results for the first ROI come through, but a JavaScript exception pops up instead of the second ROI results. All the images I am processing have the same file structure and naming system, and I believe the creation of the ROIs and RNL clusters has been pretty consistent for all images. 

The exception always begins with the line “java.lang.ArrayIndexOutOfBoundsException: 784”, although the number does vary and is not always 784. 

I’m using MacOS with the M1 chip, and I am wondering if this might be causing some issues, or whether this error means there is a problem inherent within some of my images/the way in which I am processing them. 

I also have a second, smaller question. Are there known computer memory requirements for modelling higher acuity levels? I am unsure if I need more computing power or whether, again, I am just using the toolbox wrong. Most of the time when I attempt to model acuities above the default 6 cycles-per-degree I run out of memory very quickly (ImageJ is currently allocated up to 6000mb). 

Thank you!
