For retinotopy, I find it convenient to use the sphere surface. It does not
require a cut down the middle of V1 and it is flat enough to easily draw ROIs.
Also, in my experience, the patch flattening algorithm often produces poor
results (e.g. large distortions, twisting).

Using QDec, I've created an ROI label (lh.G_cuneus.label) and a .stats
file (lh.G_cuneus.stats) that corresponds to this ROI for each participant
in my group. Is there a quick way to compile cortical thickness data for
this ROI from all participants? The manual suggests using aparcstats2table
but I
I agree, sometimes this happens in the inflated surface and I don't think
it's cause for concern

When you look at the case in tkmedit, in that same area, do you see an error?
Looking at your snapshot, it looks like it could be normal.

Dear FreeSurfers,
We are comparing two methods to measure the volume of a subcortical structure
(our method and FreeSurfer). We want to compare them spatially, by doing a
voxel-based analyses.
We thought to isolate the structure from the aseg.mgh as well as our own
structure. Then we smoothed b

Hi Bruce, et all,
Is it possible to run mri_ms_fitparms without motion correction, if
your input images are already in register? It seems like it would
save quite a bit of processing time, but the usage help isn't all that
useful (looks like there are a lot of hidden options buried in the

Thanks PPJ,
I have made a fast search in Amazon's page and via google and I did not
find it. Do i have to be registered to find it? Can anyone use a copy of
your virtual machine, or do we have to create our own and then, upload
it to Amazon?
Thanks again.
Fidel.

Yes. But that machine distributed by FreeSurfer is the one with full GUI to
run under Windows.
I have a machine for cloud processing in Amazon EC2 (you can look up for
FreeSurfer DMI in Amazon EC2)

Hi all,
I have been trying the virtual disk image, and it works well.
Nevertheless, I think that more than 7GB is a lot of space if somebody
wants to use it as a Virtual Machine in a cloud environment, in which
you are charged for used storage and maybe for used bandwidth in the
data communication
Lijie,
I don't know what the matlab regress() function does. mri_glmfit is just
solving the GLM equation, which you can do easily in matlab:
beta = inv(X'*X)*X'*y;
try that and see if you get the same as mri_glmfit.

Hi all,
I'm working on a group analysis using mri_glmfit.
In analysis directory, I got a X.mat file which containing the matrix X (
size 50x4 ) used to regress analysis, also the beta value from beta.mgh
file.
Strangely, I loaded the X.mat in Matlab and recalculated the beta using
function regres
