In macro going through slices, Geodesic Distance Map (2D) stops after the first slice about morpholibj

Hi,

well, this seems to be strange... I do not have clear idea right now.

Just to clarify, what do you want as output? Another 3D stack containing the concatenation of each slice processing?

Yes, exactly! My plan was to duplicate the GDM result into another window for the 1st slice, and then append the results from subsequent slices to this window to form a 3D stack of 2D-GDM results.

I found a work-around since the first posting: after each slice's processing, I could save the result into a TIFF (i.e., one TIFF per slice) without interrupting the for loop, and then import the 2D TIFFs as a sequence. But of course it'd be nicer to not have to have this intermediate step.

Thank you!

Forgot to mention that I have an almost identical experience with applying Marker-Controlled Watershed (MCW) on a series of 2D slices from 3D stacks input. And the same saving-result-into-one-TIFF-per-slice workaround works. The only difference is that for MCW to work in 2D mode with 3D stacks as inputs, I had to duplicate the slices of the same slice# from the input stacks and use the those slices as input to MCW; just setSlice(i+1) wouldn't be enough, which is fine.
