Just for you Paul ---
New environment variable AFNI_SLAVE_THROLAY will initialize the slaving relationship between the overlay sub-brick index and the threshold index (which can later be changed in the GUI from the Index popup choose or the threshold slider popup menu). You can
set this variable (before starting AFNI, in any of the usual ways) to
'==' *or* 'OLay' ==>> threshold index = overlay index
'+1' *or* 'OLay+1' ==>> threshold index = overlay index + 1
ANYTHING ELSE ==>> threshold index lives a free and wild life
The source code afni_src.tgz is available now. I won't do a full rebuild tonight for various reasons, but I figure you can rebuild on your own at your leisure.
See you in Milano?
