Hi - you're right that it won't correctly process these "0" labels for
the label atlases - though that wouldn't make sense to select anyway
as they correspond to the background.
Thanks for pointing this out - I've amended Featquery so that it
doesn't show the "0" label option for the labels atlases.
Cheers.
