Hi Matthew,
Thank you for your input.
The ROIs were downloaded from a probabilistic atlas (
https://scholar.princeton.edu/napl/publications/probabilistic-maps-visual-topography-human-cortex)
and are defined in anatomical (MNI) space.
When I used fslhd, as you have suggested, it actually seems that the transformation I applied on the ROI brings it to the same space as the functional scan. Nevertheless, as I described in my previous message, the featquery fsl doesn’t work.
Just a thought, is there any possibility that the transformation that I applied on the ROI file, makes the fsl read it as a functional, rather than a structural scan?
see the top lines of the fslhd for a reference:
