Thank you very much for the idea Nick,
this explained everything.
In qdec red means XY
we didn't notice the thickness data on that plot at first :(
Have a wonderful week !
Sincerely,
Alex.

Hi,
We have experimented a little with different ways of computing the
p-values in a GLM analysis based on FreeSurfer data.
The way the Matlab reference implementation (fast_fratio.m) handles a
situtation where the residuals are exactly zero, seems to be to set
those vertices to F = 0 and p = 1.
When the residual variance is exactly 0, this is what the matlab code.
In the C implementation,
if (glm-rvar FLT_MIN) glm-rvar = FLT_MIN;
which will have similar results.

Hi Freesurfers,
When conducting ROI analyses in Stable 5, is there a way to generate
a mean functional baseline offset value within the ROI which can be
used to help calculate percent signal change? This would correspond
to the value from row 4 in the output file generated by
wang,
i think having the imported roi thickness data in your qdec.table.dat
file is confusing you. you should just delete that data from your
qdec.table.dat, keeping just 'fsid' and 'addiction' columns. from
looking at your analysis (which appears you have done everything right),
it is not used
Hi,
I have recently installed freesurfer 5.0.0 on top of a Xubuntu Linux
distribution on an virtualBox/WIN XP computer.
I can run freesurfer without a problem.
My problem is with accessing Host drives from linux system. How am I going
to get the image data to my linux virtual system if I cannot
saad,
i dont have the information directly on-hand, but in your virtual box
configuration (independent of freesurfer) there should be an option to
map a USB drive into the linux virtual machine. others have done this
successfully. you'd have to google the help docs for your virtual box
to learn

The NIfTI committee are proposing the creation of a NIfTI-2 format that
