Hi all!
I am a new ImageJ user trying to count punctate ROIs in a z-stack, and
after experimenting with different plugins have found that 3D Image Suite's
Spot Segmentation tool works extremely well. However, NullPointerExceptions
(pasted below) seem to consistently be thrown just after the 3D ROI Manager
is opened. This occurs whether I open and run 3D Spot Segmentation from the
Plugins menu, or use run("3D Spot Segmentation", ...) in a macro. Just to
make sure that this was not due to any quirks in the way in which our
images were taken, I tried this on the example stack 'Confocal Series',
using the spots in the red channel to generate the seeds and determine
ROIs. The exception exists for z-stacks of 8-bit and 16-bit formats.
Despite that, the segmented stack generated, as well as the final count in
the ROI Manager both seem correct, and the exception does not interrupt the
loop in our macro, so should I be worried about it at all? Any advice or
suggestions would be greatly appreciated!
Best,
