This is the analysis used in the manuscript from my postdoctoral work with Caetano Reis e Sousa.
I can’t take the credit, it was designed and written by Rob Jenkins from the group of Erik Sahai.
It’s a very neat little script which will analyse the spaces between objects, by fitting a series on circles of decreasing size, and then presenting the results as the area in the image covered by which radius of circle. The results look like this when used on images of the fibroblastic reticular network in mouse lymph nodes.
