Toblerone is a new method for estimating partial volumes on the cortical ribbon using surfaces as input (eg those produced by FreeSurfer). Evaluation has been performed using both simulations and subjects drawn from the Human Connectome Project. The estimates returned differ from those produced by existing tools such as FSL's FAST, which will have implications for the analysis of functional imaging data (notably ASL). A preliminary analysis of an ASL dataset has been performed using Toblerone's PV estimates.
