Dear freesurfer experts,
I am trying to do cortical thickness-age correlation in Spinocerebellar
ataxia patients (SCA1 and SCA2).
## I successfully ran qcache command on these 10 subjects of SCA1 and SCA2.
##Since my discrete factors are *Gender *(Male and Female) and* Diagnosis*
(SCA1 and SCA2),
Dear FS experts,
I am new to freesurfer and have a few basic questions.
I have a sample of 8-17 year olds in which I will be looking at both cortical
thickness and subcortical volumes. I understand that the surface-based
registrations seem to be fine for this age range (as per Ghosh et al,
You may find this paper useful:

Authors describe there some measures such as Euler number and #8220;Contrast
to Noise ratio (CNR). Actually, they dont belong to QA package, but they are
definitely worth looking at.

This type of design is not suitable for optseq2. Furthermore, you only have
100s of task and almost 300s of scan time. This will lead to lots of empty
space. You really need more than 2 conditions per event type.

Are there any flags that are helpful to add when dealing with these images
with gadolinium?

Hello,
To this point, I have been able to successfully register Myelin Water Fraction
(MWF) scans to Freesurfer Base Space in the longitudinal pipeline (thank you
for the help with that!).
What I would like to do next is use Freesurfer ROIs to automatically extract
the mean intensity of the
Hello,
I'm trying to convert an ROI mask I created in MNI305 space to MNI152. After
running MRI_vol2vol the registration looks off (too anterior).
Here are my commands:
