Hello,
I would like to measure the ring spacing of fish scales and otoliths
with Image J (same principles of tree ring analysis apply). In the past
I have used Optimas (now ImagePro) software to measure the ring spacing
of otoliths. For that I was able to run a transect from the core of the
otolith out to the edge and place hash marks at each ring. Optimas would
then provide me with data on the distance between each ring. I have yet
to be able to figure out a way to do this in Image J. It would be ideal
to figure out a way to automate the process (i.e., automatically have
ImageJ place hash marks at the rings along the transect). As you can
probably tell, I am VERY new to ImageJ and would really appreciate some
feedback. Also, if you know of any good macros or plugins out there,
please let me know.
Many thanks in advance,
