Hi Doug,
What is your preferred citation for FsFast (used for resting-state)? I
couldn't really find a clear answer in the Zotero library or mail
archives.
Thanks and happy holidays!

Dear Freesurfer experts,
I would be very greatful if you could help me with three (probably basic)
questions regarding an mri_glmfit design.
For the design and contrasts I used FSGDF. I have a 2x2 factorial design with
one covariate (age). I specified all four groups (A1B1, A1B2, A2B1, A2B2)

I don't think we have a tool to display the color wheel in a volume.
FreeView might be able to do it. For the color wheel in tksurfer, you
are looking at the angle file (one for eccen and one for polar), so you
would map them. You can run mri_surf2vol something like
mri_surf2vol --surfval
Hi Doug,
Thank you for your quick response. Concerning question3, do you mean that if
there is an interaction with age, it is all right to use DODS (without
stratification)?
Thanks, Maaike

I did not mean that. If there is an interaction then there are issues
of interpretation when comparing means (ie, offsets) since the
comparison then depends on the value of the covariate. Eg, at age 70
there may be no difference in offsets, at age 50 there may be a
positive, then negative
Hi!
When looking through the brain scans, I've noticed that the lines outlining
white matter intersect with lines outlining the gray matter. How do I fix
this problem?
Thanks,
