Graham,
1. You're right: BrainFish isn't mapping negative activity as
intended. I just mapped
CARET_TUTORIAL_SEPT06/BURTON_04_VibroTactile_EARLY_BLIND+orig.HEAD onto
PALS_B12 711-2C using BrainFish, and although this volume has big
regions of negative activity, the metric file gets assigne
The MCW BrainFish algorithm was developed by a group at the Medical
College of Wisconsin to meet a specific need they had. Unless they
tell me it is not working correctly, I am not going to dig into it.
I believe the enclosing voxel algorithm is the most popular, you
might consider it.
Folks:
The brainfish algorithm is described here:

... as picking up negative voxels if there are no positive ones
around. Couple of issues:
1. We don't seem to be able to get negative voxels to appea
