Hi there!
I have a couple of questions about grain analysis (I’m a new Gwyddion user so I
apologize for these really basic questions):
1. Regarding the orientation of the major ellipse, when exported the output
data are expressed in φ angles. Is it possible to covert these values in
degrees and how?
2. I need to get information about grains shape factors. Which one do you
reckon is the best with the data available in the grain distributions?
I am trying to calculate the circularity through this ratio:
C= 4πA/P^2 (A= area, P=perimeter) .
In this case I am using the projected area (A_0) and the projected boundary
length (Lb_0) but I am not sure if this approach is right or there is a better
way to do it.
Thanks
