OrientationJ tutorial

Hi–
I am new to ImageJ and need to do analysis on collagen fiber orientation/ diameter/ any other useful measurements. Initially, I was trying to use DiameterJ but I have been having trouble getting that to work. I know that OrientationJ has some overlapping plugins and has useful tools regarding fiber orientation, but it is hard for me to figure out what all the features do/ what information I need to provide for accurate results.
Does anyone know where I can find a tutorial or some sort of “how to” guide?

Thank you very much.

What exactly do you need to measure for your analysis? Perhaps you can share that information - as well as an original image file?

The homepage for OrientationJ is here: http://bigwww.epfl.ch/demo/orientation/ If you have specific questions regarding functionality - you can perhaps as @daniel.sage directly here?
