Dear Colleagues, I forgot you are not all familiar with the anatomy. The upper jaw is the upside-down green U and the two green vertical bars at the sides are the vertical rami of the mandible.

I want to select gray levels 61-109 to segment the bone (attached Threshold selected.png). My macro code is minimal File.openSequence("/Users/douglasbenn/AI/Both Jaws/BothJaws28/BJ28_tiff/"); run("Auto Threshold"); run("Convert to Mask", "background=Dark calculate"); Inside of segmenting the bone I create an image of all the foreground tissues (attached Threshold applied.png). What am I doing wrong? Thank you. Douglas Dr Douglas K Benn DDS, PhD, Dipl.
