Dear FSLers,
I want to run siena to compare a clinical group and a control group with
scans four years apart. The scans were of lesser quality in the first
than in the second wave. As a first test, as I am no expert, I have run
siena on two subjects. I had attached the gifs of the results but it did
not make it to the list since the message was too large.
My questions are:
1. I would like to know if my results look reasonable, is there a drop
folder for somebody to have a look at them? and is the red outline the
second scan overlayed on the first one (or the reverse)?
2. What should I do to improve the results and apart from looking at the
GIF what is the best way to assess the quality of the registration?
3. At the end of processing siena spits out -6.332, is it the volume
difference in mm3? (where can I find all the volumes?)
4. I have looked at the siena website, searched for tutorials,looked at
the mailing list, read the attached pdfs, and browsed the wiki but it
seems that there is not enough detailed step-by-step information for a
new user like me. Is there a detailed tutorial somewhere dealing not
just with process but with quality of output and what to do to improve
it?
Thanks very much for your continuing support
Nic
