Hi Bruce
Thanks for your help. This is what I have done:
- I used recon-all to define 84 brain regions.
- I ran tractography with these 84 regions as seeds.
- Then I used network-based statistics to compared the obtained connectivity
matrices (84 x 84) between two groups. To visualize the output, I need a txt
file including the MNI coordinates of each node.
Please find attached my seed/node list. I simply need the x, y and z value for
each node.
Many thanks for your help, much appreciated.
André

Hi Andre
are you going to do a group analysis afterwards, or so you just want the
node coords? The fsaverage subject is already in MNI coords so you can
transform to it I believe (Doug can confirm).
cheers
