Andrea and Steve,
Many thanks to for your suggestions. Íve made some tests with
siena_flow2tal (it took me a while to figure out that the script needs
some of the output from SIENA first) and now I get a threshold number and
a *_FLOW_DIL and *_FLOW_TO_TAL images that I dońt know how to interpret.
I understand that a posterior voxel-wise analysis is a way to go but I was
thinking of a way to segment directly into ROÍs the
IM1_HALFWAYTO_IM2_RENDER output from SIENA??
On the other hand, the solution of J Chen is really neat: measuring the
atrophy in mm of cortical thickness change. That́s a much more practical
result and easy to interpret for a clinician like me. The problem is how
to get those numbers from SIENA output??
Does the script SIENA_FLOW2TAL include anything to do that?
Many thanks in advance!
Santiago
