Hi all,
I've written a function that reads *.fsaverage.mgh files into the free
statistical software environment "R" (http://www.r-project.org/) and thought
it might be useful for other users. Apologies if this has already been done,
searching for "R" is kind of non-specific. Any feedback is welcom
You can edit the label by hand to only include one vertex. If you got
the label from a call to mri_surfcluster, then surfcluster will output a
summary file with the max vertex in each cluster.

Thank you so much for your suggestion!
Doug, is there a way to modify the mri_segstats command from before to specify
coordinates of a vertex (say the peak from the ROI in my contrast)?
Thanks!

Hi
I have tried with driver 260.19.36 with a similiar result. The complain
in this case is that MRISallocCudaVertices: cannot allocate device
memory !: all CUDA-capable devices are busy or unavailable.

Hi Gallen,
I suggest that you extract the values across subjects at a single vertex
in fsaverage space, and then attempt to duplicate FS's uncorrected t-
and p-values at that vertex with your SPSS model. Those HAVE to be
identical if you are truly using the same model (unless there is an
unknown
Thanks for the reply!
I'm fairly certain that I'm using the same model. In Qdec: 2 discrete
variables, 1 nuisance variable. In SPSS: a univariate ANOVA with 2 factors and
1 covariate.
I understand the difference between Qdec and SPSS may be because Qdec looks at
the entire cortex. Are there any
Hi Jeff,
it is the talairach.xfm file you need to check. The wiki says
http://surfer.nmr.mgh.harvard.edu/fswiki/eTIV
To check the quality of the registration file talairach.xfm file:
cd $SUBJECTS_DIR/subject/mri/transforms
tkregister2 --xfm talairach.xfm \
--targ $FREESURFER_HOME/average/RB
There's something strange going on. Did your label come from the right
hemisphere? The first coordinate of all the points is negative,
indicating that it is on the left side. Which MNI atlas are you using?

Hi jeff.
Probably your Talairach registrations fail. There are several different maps. I
don't remember which one is the one used for the eTIV but it is documented on
the wiki. You probably looked at the wrong transforms.

It's a numerical issue having to due with adding very large numbers with
very small ones. You don't get exactly the right number out, so there is
a small error. Over many operations, these errors accumulate.

Oh, sorry, Greve. I misunderstood your suggestion.
Now I get the same resulte in both mri_glmfit and matlab. Thanks a lot!
But there is still a question about how it happened. Why I have to do so to
get the correct result? There is nothing relevant between the number scale
of one variable and the b
