Hello,
I require values (total volume) for the prefrontal cortex. I see labels for
G_frontal_middle and G_frontal_superior in the lh.aparc.annot files - are
these correct to use? If so, could I add up the values for these to get one
total volume for the PFC?
Thank you,
Fatima
look in the subject/stats/?h.aparc.stats file

It was created by mapping all the individual asegs of the

most frequently occuring label. It should only be used for display
purposes.

Hello,
I keep seeing a snowy background for my T1 structural images.

Hi all,
We have used mrivol2surf with the output of bbregister to transform an
individual subject's fmri data into the coordinates of the anatomical used
to generate that subject's surface. We are happy with the accuracy of this
registration. However, we are stuck because as far as we know
Hi Dave,
001.mgz in SUBJECT_ID/mri/orig/ looks okay but 002.mgz looks strange,
which I think is the reason for what you are seeing in T1.mgz.
Did you collect 2 runs for structurals. Can you point me to the dicom files
for this dataset or the scan log.
Sita.

We have another question that is very related, so I will ask that at the same
time:
We have a region of interest defined on an individual subject's surface. How
can Freesurfer translate that ROI into the coordinates of the original fmri
data? It's clear to us how to get from fmri to the
Hi all,
I would ask you about freesurfer and retinotopy. I'm going to begin the
analysis of some retinotopic data. I would ask if you know if the
retinotopic analysis made by MGH freesurfer is qualitatively comparable to,
or it's good as, that made by USCD freesurfer (old freesurfer).
Thank you
what do you mean by Old FreeSurfer?

Dear FS experts,
could someone advise on how to create from an individual thickness file
(?h.thickness) a standard deviation or z-score map of the thickness with
respect to a control group.
Thanks, Michael

Hello,
I am wondering if it is possible to calculate t-values and significance of a
whole ROI in qdec, version 1.2. Right now, I have no problem doing it on a
point-by-point basis, but I want to do whole ROI analysis within qdec. For
example, I want to know the p-value of the whole
