Particle alignment

in my images I have structures containing several particles. I first identify the structures, then I apply a mask on my particles image using the structures. Now, I want to know if the particles are aligned or not in each structure. Do you have any idea how to realize this analysis?


Some clarification: I’m not sure what you mean by whether the particles are “aligned.” Specially, aligned with respect to what? To each other? To another feature within the structure? It might be helpful to post an example image with an explanation of what sort of alignment you are looking for.
