OK - that's good then, a much simpler workaround. Out of interest - was it
just that you were using a very highres standard brain? For the record, we
decided to use a 2x2x2 standard brain (as do SPM etc) not just because
that was the current default MNI template but because we felt that the
various forms of spatial variability at the group-level didn't "deserve"
higher resolution than that.
Cheers.
