The 27307 x 6 was originally done to be able to store data in nifti and
analyze formats. They can be reshaped into a single vector of length
163842. When you load it into tksurfer, do you set the threshold to
something very close to 0 to see if your values are just too small? Is
everything 0 in
yes (but make sure to make backups).

what do you mean that you were not able to overlay it on the surface?
What is actually going wrong? It looks like mri_vol2surf complete

what do you mean by making the pair-wise all at once? You'll have to
correct for multiple comparisons some how. If these are clusters, then
it is probably better to correct on a cluster by cluster basis, then do
a final correction over the three p-values you get.

Hi surfers:
I was trying to convert a volume dataset from PET to fs surface template.
The command I used is the following:
mri_vol2surf --src pet2t1.mgz --srcreg register.dat --hemi rh --o
./sig-rh.mgh --out_type mgh --float2int round --trgsubject ico --icoorder 7
The output file here i
Thank you for you help Doug, of course I can explain it better
Let's suppose that resulting from the ANOVA I get three significative areas
(i.e. enthorhinal, parietal and frontal), do i have to make the pair-wise
comparisons on the three areas at once?, or can I perform a pair-wise for

Hello,
Version 4.2.0 was used to start processing data for a 3-years project. We
are still acquiring data for the project, and would like to start using
version 5.0.
For some of the subjects already processed, manual talairach alignment was
performed with tkregister2, and as I understood when rec
you could tesselate the surface of the aseg cc and measure curvature that

I'm not sure what you mean. Can you elaborate?

One more, Do I have to perform the pair-wise comparisons onto all significant
areas all together?, or can I make it on each one separately?.

no, those are not valid. cc is not a cortical structure. use the
measurements from the aseg.stats file (for volume only).

Hi Nick:
I processed around 183 brains using 4.0.3 a few years ago. I have numbers on
the CC volume, thickness SA and Curvature. Are these not valid anymore?
thanks,

corpuscallosum was removed from the parc stats because it is not a valid
cortical structure (the thickness measure was not applicable).

Yes, restrict the pair-wise comparisons to areas where the ANOVA is
significant.

The problem is in the surf2surf step implemented inside vol2surf. You'll
need to do it in two steps. First, vol2surf to the native surface, then
surf2surf to fsaverage but specifying --mapmethod nnf

Hi,
I haven't got a reply, so I thought I repost this:
Is it a known problem that when doing a nearest interpolation from a
volume of integers from a subject's anatomical space to the fsaverage
surface using the mri_vol2surf flag results in non-integer output, or
am I doing this wrong (see
Dear FS experts,
We are using the 4.3.1 version of FreeSurfer, and we have noticed that in
the lh.aparc.stats/rh.aparc.stats file there are 35 structures calculated
and not 36 structures, only corpuscallosum is missing.
We have also compared it with an old subject processing (using 4.0.2 version
We are hoping to view a Freesurfer session running on Fedora 13 using
NoMachine. So far, we have not succeeded. Freesurfer runs fine locally,
and NoMachine is otherwise working fine to display output. However, when
running qdec (for example), we get the following error:
