You can do this on the surface for the cortex, you will probably want to
use -cifti-separate to get the left/right pieces as separate files, then
you can use -metric-math for difference/thresholding/masking/etc, and then
-metric-vertex-sum with an -integrate option to get an answer in terms of
surf
Why wouldn’t you do this in CIFTI space?

Matt.

Dear HC
Dear HCP users,
I'd like to investigate lateralization of activation in task data in some
subcortical and surface Brodmann areas. Generally, as far as I know, this
is usually done by comparing % of voxels activated at some threshold in a
region. Is there any straightforward way to do this in workb
