Re: [Freesurfer] Tracula and Qdec

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?

I am looking at Average AD in these tracts.

thanks,

  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
