Hi Steve,
Thanks a lot for this patch! I think I have to re-run the analysis in order
to get the match with the clusterlist (since fslview still lists a different
voxel at that coordinate).
Should this not work for some (internal) reason, which coordinate should I
enter into featquery: that which I found in the clusterlist or the one I
found myself in fslview (with the -2mm shift in the Y-direction, but the
right Z-score)?
Cheers,
Rutger.

Hi Rutger - I just tested this using the latest versions of FEAT and
fslview and it all looks fine - I suspect that you don't have the very
latest versions?
In case you missed any patch announcements; the latest patch is:
