I am trying to measure axons that suddenly change direction and are made up of connected straight line segments. The line segment tool is perfect for measuring length; but I also noticed that each time an individual line segment is made, imageJ gives the angle of the individual line segment with respect to the positive x axis of the image (but it does not record it). I was wondering if it is possible to get an average angle of the connected line segments? I could not find any script from a google search.
If nothing else, I can always do a second measurement of the angle by approximating a “line of best fit” on the individual axons. I was just hoping I could speed up the process by knocking it out with one measurement.
