Emily,

Did you use TENT as basis function to estimate BOLD response at the single subject level? Are you trying to average those betas associated with the TENT basis functions for each stimulus condition?

Do you mean that you have two probability values at each voxel, each of which is the likelihood the voxel belongs to one of the two subregions?
For what purpose do you use the resulting "weighted" average?
