Hi Ariel, I second Bruce; we don't have a pipeline to directly measure the subfield thickness. We have, however, tried an indirect volumetric method to compute the thickness (http://nmr.mgh.harvard.edu/~koen/IglesiasNI2014.pdf, the "Experimental setup" section). It requires a (preferably soft) segmentation of each subfield, parameter tuning, and skeleton computation for reading the thickness values. So if you're willing to try it in spite of it not being so straightforward, I'm happy to share the tissue thickness measurement codes.
