Hello,
I was wondering if anyone has used the nlmefit function in Matlab to model
longitudinal FreeSurfer data? If so, is there code available that could be
shared?

Thanks Jorge!
In our case, at step 4, an F-test does show
this scenario is not possible/doesn't make sense. Do you have any
advice for looking at group differences in our situation?
Thank you for your time/help.

I'm sure that there are a number of ways you could do it. I would suggest,
however, making a coronal cut for your frontal labels at Talairach coordinate y
= 26, so that only ‘prefrontal’ regions are included - this conforms to the
conservative Talairach criteria described by Rajkowska and Goldma

Hi Sara, I'm not sure what you are trying to do. Are you doing a volume
or surface-based analysis? If surface based, why do you need to convert
it into the volume?

Hi,
I would like to create an overlay from a number of labels from the standard
2005 aparc in order to perform an fdr correction of a significance map using a
mask to restrict the search space. I would like to do this with fsaverage.
As far as I can tell, there is no label or annotation to surf

Yes, I would demean before computing age*age. Is pubertal status a
continuous variable? If so, then demean that too.

Hi,
I have a follow-up question about demeaning, specifically applied to running
linear mixed effects models.
For example, we have a design matrix X with the following columns:
intercept (all ones)
age
gender
age*age
pubertal status
If we want to look at the effect of age*age, controlling for p

Hi Sarah,

separately or individuals that have had 1, 2 or 3 scans?
Is there a simpler way of doing this though?? I feel like we're making things
more complicated than they need to be!
Thanks,

Hi Sara,
yes, should work, just make sure that all cross are 5.1
Hi,
RE the below post, we have longitudinal data from three time points, but a
number of participants have scans for only one or two time points. We've done
all of the cross-sectional analysis (including a lot of manual editing) and are
ready to run everything through the longitudinal stream. O

Just wondering if Nick or one of the gcut developers could help me with
