Hi Sylvain,
Yep, you're correct, FEAT assumes you're putting a brain image into it ;-)
Probably the simplest workaround is just to pad with an extra slice, with
values set to lower than those you want to keep, using avwmaths and
avwmerge etc....i've looked in the FEAT tcl and it's not trivial to change
there - the other workaround would be a small edit in ip.c and to
recompile that.
Cheers, Steve.
