Hi Doug,
I'm a little confused as to how to assign functional data to the fsaverage
space.
1) Do you mean just change each subject's subjectname file to fsaverage and
then do the same thing as before for each person?
2) Also, when I specify the analysis do I change -rtopy.self.lh to
rtopy.fsaverag
Dear FreeSurfers,
I am new to Freesurfer and attempting to run a very basic analysis, but
am finally stuck after trying 3 alternative ways of displaying the data.
Any help would be greatly appreciated!
I have 4 wedges/quadrants (no expanding rings), and want to show areas
responding to each

If you want to combine across subjects, then you need to run the
analysis on fsaverage (ie, rerun preproc-sess, create a new analysis,
run selxavg3-sess, and then isxconcat-sess).

I don't know how the PALS atlas was created. The method to create the v1
label was validated by Oliver Hinds (don't have the ref handy).

Hi Heather,
I think the answer is that we don't really know. Hopefully the level at
which we cut off the brainstem is consistent as it's based on the curvature
of the enclosing surface that we fit, but we've never looked at it
thanks

p.s. the first one at least looks like so much subject motion that the

Hi Warren
it's always hard/impossible to diagnose from snapshots. Can you upload an
entire subject's dir to the file drop?

hi folks,
do you happen to have any tool/script that produces a graph of aparc region
neighborhood? with perhaps the edge weight being the length of shared
boundary.
cheers,
