Hello Petsurfers!

A few of my subjects ended up with vertices that had outlier PET values after I followed the PetSurfer steps. Most of the binding potentials are in the range of 0 - 3. Looking at the histogram though there are a couple of vertices with values around -30. First of all how can I deal with this? Can these voxels be excluded from the data, and how? Secondly, does this mean that there is something not right with my parameters for mri_gtmpvc? 

Cheers,

Shane
