Hi Gabriel,
Thank you for your reply. First thing I did was try out the domes
plugin. Unfortunately, it appears to be broken in the latest Fij
distribution. I reported it with the Fiji bug reporter, but I figured
you might want to check it. I put it on the list because I am sure that
lots of people use your morphology plugins (they are the first thing
that I add to any new installation...)
GrayScaleReconstruct also seems broken. Most of the others work -- I did
not have a chance to test them all.
Best regards
