Dear all Freesurfer users,
I have a few questions regarding wm.mgz edits.
I am very new to this area and have only recently started using Freesurfer so
please excuse me if my questions appear naive or misinformed.

Dear all,
I have a quick question regarding the appropriate design (DOSS, DODS, SOSS,
SODS) to be used with QDEC when comparing LGI values for 2 groups (patients
and healthy controls). I have noted that a number of publications have used
DODS when comparing LGI values between 2 groups while contro
Dear Freesurfer experts,
I have a quick question regarding the appropriate design (DOSS or DODS) to
be used with QDEC when comparing 2 groups for cortical thickness and LGI
values.
So far I have used DODS first to look for an age-cortical thickness
interaction in both groups. I used the real ages

Dear Doug,
thanks again.
Will look into which is the best for LGI (if any).

Dear FreeSurfer experts,
I ran my group analysis using mri_glmfit and found a number of significant
clusters showing cortical thickness differences between 2 groups. I used
tksurfer to visualize the results and used FDR to correct for multiple
comparisons.
My question is about how do I correctly

Dear Doug and Bruce
I have a couple of questions regarding multiple comparison correction.
Any help with this would be really appreciated!
I am conducting a cortical thickness analysis between 2 groups (patients vs
controls).
My understanding is that first I should check for an age-cortical thi
