Hi Kersten & Martin,
I just wanted to ping this thread again, as I'm still unsure about my pcor
value (4.4) that I'm getting. I've seen other posts where the threshold (thmin)
value specified in functions such as mri_surfcluster are around 2

Hi Kersten,
Thanks for this helpful summary.
It seems then that it’s best to apply the threshold to the *sig.mgh file and
visualize its results since it contains the sign that specifies the direction
of the interaction effect. Assuming this is the

Hi Dan,
excuse the late response; regarding your remaining questions:
1)
This sounds correct to me, pcor is the corrected threshold that can be applied
to the sig.mgh files.
2)
If I am not mistaken, the spval file should be equivalent to the sig
Hi Dan,
I have not worked with this code in a decade, but Kersten in my group maintains
our R package of it ( see https://github.com/deep-mi/fslmer ). I will bring
this to his attention.
Basically I think you determine the joint p-threshold across hemispheres and
convert it to FreeSurfer ( -

Hi Martin,
Thanks for the response!
After my original post I went through things more carefully based on my two
original two questions and made a follow-up post here
Hi Dan,
a) yes
b) yes

Hello,
I wanted to bump this post once more to see if I can get any guidance here. I
believe I am close to solving this problem, but I have two lingering questions
that are preventing me from moving forward.
Thanks again.

After spending additional time working through this, here are the current steps
I’ve taken for running a mass-univariate LME longitudinal analysis on both
hemispheres:
