Hi Alan - Sorry, tracula doesn't do voxel-based analyses, only
tract-based.

Hi Anastasia:
Yes I generated the left CST on a single subject using the Freeview -tv
option. But my boss wanted to know if it was possible to do a voxelwise
group analysis and show mean differences on a single inflated brain.
thanks,
Alan

I see, then it's an ROI analysis, where the tract is the ROI.
Isn't it sufficient for you to visualize the tracts in an
example subject with the -tv option in freeview? What would you
like to do beyond that?

Hi Anastasia:
I am looking at Average AD in these tracts.

Hi Alan - Are you looking at average AD over
the whole tract, or
AD along the tract?

Hi Anastasia:
Thanks for your quick reply. We would
like to look
at the left and right
Cortico-spinal tract AD between the
groups. Also
left and right ATR AD if
possible.
thanks again,
Alan

Hi Alan - Glad to hear that you
have an
interesting finding! Can
you describe what type of thing
you want to
visualize a bit
more? If it's not on the surface,
freeview
will more likely do
the trick rather than qdec.

Hi Anastasia and
FreeSurfers:
Is it possible to model
Tracula data on
Qdec? I have
some interesting
findings in FA and AD
between two groups
that I am
hoping to visually
represent on a single brain.
Any advice would be deeply
appreciated.
thank you,
Alan
