Here is the 3dfractionize command I used:
3dfractionize -template BN1+orig \
-input mask_ACC+tlrc \
-warp Struct+tlrc \
-prefix fract_mask_ACC \
-clip 0.2
I did not use the "-preserve" option. Should I have? When I look at the ROI in +tlrc and +orig space they look like you'd expect (is there something specific I should look for?).
The problem comes when I use 3dmaskave, then I get a voxel count that seems more like it pertains to a +tlrc dataset than the +orig I want:
3dmaskave \
-mask fract_mask_ACC+orig \
-sigma \
stim_47_BN1+orig
Sorry to bother you with this, especially when it seems so straight-forward, but I just can't figure out what's up.
