In the FreeSurfer reliability paper, you recommend linearly registering the
subject's meshes to each other and point to the Jenkinson paper. How actually
is this done with FLIRT?

Once FA results are co-registered is there an easy way to use the wmparc.mgz to
collect the mean FA values by region, or do we need to treat it like FMRI and
make masks of each parcel and collect each mean separately?

Hi,
Computing individual fMRI analysis (several runs) and looking at the
design matrix
(X.mat), I saw that only one regressor represents each condition. I
was expecting that
the number of regressors concerning a condition would be the number of
runs (as SPM).
There are "inter-run effect" re
Hi,
when I launched the command tksurfer to see the constructed pial surface,
only a very small part of the surface can been seen in the window.
I do not know how to fix the problem.
Thanks!

If you have an Nvidia graphics card, you will need to update the driver.
Try running nvidia-installer --update, as root (preferably have your
sysadmin do this).

Another option to VNC is freenx.

Hello,
I was curious if anyone had specific recommendations for correcting ROIs
for total brain volume/ICV. From what I can tell, some groups correct each
ROI by computing a ratio of ROI/total_brain_volume. Other groups, however,
enter total brain volume as a covariate in their statistical mod
I have not looked at it before, but I do see that it exists on some of
our subjects and not on others. Not sure why, except that it is a small
structure that maybe gets crowded out.

Hi all,
I'm trying the new version of FS for a study on multiple sclerosis that our

Jennifer,
I think you have the PowerPC build, but your machine has an Intel
processor. Try getting the one named:

Although in principle (as stated by Apple) PowerPC code can be emulated
on the Intel processor, in practice it looks like i

This may be a newbie question. I am trying to evaluate regional

cannot figure out how to tabulate all the white matter volumes. I see
that in individual folders, there is a file called wmparc.stats. Do
