Hi Anastasia,
Thank you for the clarification! As you said, if I regress out the global FA, I
could wipe out the regional FA.
o ask that requires it.

Hi,
When conducting group-level analysis, for example comparing volumetric
differences or tractography FA across subjects between groups. How we
correct for the size of the brain when comparing volumetric differences or
correct for the whole brain FA?

What is your source data? It looks like you have two time points per
subject, but the names of "offset" and "slope" suggest some preprocessing?

I don't know what you mean, can you just send the header of the fsgd
file and the contrast matrix?

Hi,
I want to perform a linear regression for a task with 3 different risk
conditions (low, medium, high) with the following linear trend: low = 1, medium
= 2, high = 3.
Right now I'm specifying the above weighted under each risk condition in my
contrast matrix. Is this the correct approach? I
Use mri_vol2surf to convert the individual vols to surface overlays,
then use mri_concat to put them together as a multi-frame file. Or you
can use mris_preproc to do all of this. They both have --help with
more info.
