Hi - no, SIENA is for calculating brain boundary shift from two
timepoints' structural scans.
For such custom application you should use BET and FAST (with partial
volume estimation turned on) on the structural and FLIRT to get the
example func and structural spaces aligned, then avwmaths++/avwstats+
+ to extract the information you need.
Cheers, Steve.
