Hi,
I had 2 questions relating to measuring global mean cortical thickness with
the weighting factor of surface area
bh.thickness = ( (lh.thickness * lh.surfarea) + (rh.thickness *
rh.surfarea) ) / (lh.surfarea + rh.surfarea)
1.) If this weighting is recommended, then shouldn't it be performed
be misunderstanding something
Could this info be extracted with converting a surface (e.g., inflated)
with mris_convert? If so, where can I find info on how to read the ascii
surface files.
In other words, what I'm trying to do is for each vertex:

Thanks!! These options do the trick

Hi,
Is there a way to create a subject specific overlay with an intensity value
of 1 (or another constant value across the entire cortical mantle)? (I'm
thinking a command like fslmaths in FSL but on the surface for each vertex).

), and given
the outputs from mri_glmfit, it seems like it would be possible with
Freesurfer.

Hi guys,
I want to overlay an ROI mask created in FSL in the MNI152 2mm volume space
(from a metaanalysis) with the aparc labels in Freesurfer to compare the
two ROI schemes (so I can have justification for picking some of the
Freesurfer ROIs for analyses).
I'm thinking of running the MNI152 2mm
Hi,
I have two groups and two time points (pre and post). I want to investigate
group*time interactions in an fMRI task taken at both time points.
I have run all the subjects through first level FEAT analyses in FSL as
well as the longitudinal Freesurfer pipeline.
I'm thinking of registering
Hi,
I'm having trouble figuring out following problem:
For one subject (out of 200), I get the following error (this error only
persists for the right hemisphere-- left hemisphere works fine for this
subject).
mris_label_calc intersect
/SUBJECTS_DIR/sub2.long.subt/label/rh.cortex.label
it be
better to use longitudinally processed stats (as opposed to the cross
sectional stats)?
I ask because I'm not aware of any publications that do this...
Thanks much,
Mike Kranz

Hi all,
I was wondering how I could go about getting anatomical stats for the
different regions from the Choi2012 and Buckner 2011 parcellations.
The Yeo 2011 cortical parcellation files were available in the fsaverage
folders and I could get stats and labels for those, but I couldn't figure
out
Hi all,
What's the difference between the curvature and folding measures outputted
in the aparc stats files (i.e. mean, gaussian, folding index, and curvature
index)? Additionally, which measures are the most reliable for individual
differences?
Thanks,
Mike

Hi all,
Is there a place where I could find an atlas with all of the Brodmann
areas? Or is the one available with a portion of the areas the only
existing atlas?
Thanks,
Mike

. It depends on what you are after in your
analysis if you need to take care or not.

Hi all,
If I process more subjects than the recommended amount given my number of cores
and memory, will this affect the stats/surfaces or just slow the process down?
I'm asking due to the sensitivity of workstations and also I seem to be getting
slightly different stats sometimes when I
