Dear fsl group,
I am new to Featquery, and I am writing due to a problem that I have found
while recently using it.
What I was trying to do was to use a small functional mask from the
orbitofrontal cortex region (a cluster extracted from the output of higher
level analyzes) to extract values for each participant for a certain
contrast. I used lower level directories as my input.
However, when I looked at the output Featquery gave me for each participant,
I was surprised to find that the mask was empty (zeroes) for about a fourth
of them (I should mention that when binarizing the mask I tried to be as
liberal as possible).
My first thought was a registration problem, but when opening the
standardized brains of a few of the participants for whom the mask was
empty, I could not detect any inconsistencies... Other thoughts?
Thanks for any advice,
Regina
