I’m using segment statistics to use some MRI-defined segments to export some quantitative PET data. This usually works pretty well, but does not work if my segmentation is small (less than half the PET voxel volume). I suspect this might be because of the inclusion criteria - binary mode as some softwares support (example on pg 188 http://doc.pmod.com/PDF/PBAS.pdf). I think it would make sense in my scenario to use fraction mode (example also on pg 188 of the previous link). Is there a way I can use fraction mode in Slicer? If not - is this something that might get implemented?
