Dear Jodi,
You'll need to make 10 separate masks for this, as non-binary
masks are treated as weights inside of Featquery.
To take your single mask and create the other masks, you
can just use fslmaths. You would do this:
fslmaths origmask -thr 6.5 -uthr 7.5 -bin mask7
would save the image "mask7" that is a binary mask but just
containing voxels that were set to 7 in your original mask.
If you do this for all of your 10 values then you can run Featquery
with each of the masks separately.
All the best,
Mark

I would like to run featquery so that I can get a percentage signal change value from each of those regions separately. I cannot figure out how I can get 10 values instead of just one value for the average of the 10 regions. Can you please help me?
