> Dear Wayne, I don't understand the behavioral difference between older versions of imagej and last (1.49m). The dialog box “Calculate threshold for each image” no longer appears (whatever the image I use). The command Process>Binary>Convert to Mask also does not give access to the “Calculate threshold for each image” option. Similarly the macro recorder produces different macros.
