Hi FS users,
We've T1 and EPI images collected. For my analysis I want to use FS parcellated
regions (both cortical/sub-cortical regions) as ROIs (Masks) for my functional
images. Would anyone kindly let me know what is the best way to proceed. Cheers,
Sabin
Hi,
Is it possible to get over some 2D representation of the cortex (whether it's
on a plane, on the surface of a sphere, it doesn't matter (although the plane
would probably be easiest to work with)) to get cortical thickness measures
at every location?
Thanks,

Dear experts
I have created a larger number of labels on the FS_average surface and
performed an FS_FAST analysis. The main goal is to obtain a functional
connectome that contains all the possible correlations between 50 Rois in 100 subjects.
The FS_fast analysis resulted in a
establish a registration between the functional and anatomical with
bbregister, then use mri_label2vol to map the aparc+aseg.mgz into the
function space.

My desirable output would be then a .txt file that consists of merely two
columns. The first column is the subject's ID and the second is the CNR value
only, for example:
bruce 1.602
bert 1.555
john_doe 1.666
Thanks in advance.
Cheers,

Hi everyone
I don't know if someone had the chance to look at the data we uploaded
for advice to edit the recons (see below).
Thank you so much

The aseg is correct, no ventricule labeled there (I was used to that)
Hi Mohammad,
the thickness can be displayed as a map on any surface we create. We do
create ?h.sphere files by default, so you can use those if you want. If
you'd rather a planar representation you need to make cuts in the inflated
surface and use mris_flatten.

Hi Jacek
if you give us an example of what the desired output would be for you it
would just be a couple of minutes to put it in the code. Or maybe someone
can post some sed code (or some easy alternative) to parse the CNR out of
the output.

You are correct. Note that if you want to compute an average inside of a
label, that you may want to use fMRI data that is unsmoothed (even on
the surface) as this will cause false correlations between labels.

Hi Everyone,
I have been using both tksurfer and QDEC to view group comparisons of cortical

maps other than just the mean
You will need a 4 group FSGD. The interaction would be contrast 7 on the
4G web page

I can confirm this bug on Mac (It does not happen on Linux). I'll look
