Thank you very much for your valuable reply.
I still have few questions on which I would like to ask your advise:

Dear all,
I have two groups of subjects, and I want to see a difference in
thickness between them controlling for age.
I couldn't find any information in the literature on how the subject's
brains in my groups develop with age. Therefore I can't tell whether
thickness as a function of age for
Hi Tanja, you should use DODS and test for a difference between the age
slopes of the groups (ie, an interaction between group and age). If
there are no significant interactions, you should then use DOSS to test
for the difference between thicknesses.

Hi! I successfully run the preprocessing on some polarangle data
(preproc-sess -sf seesid -surface self lhrh -fwhm 5).
Now I would like to do the subtraction between some runs and then to
visualize this subtraction on the surface (so without to analyze the
data with Fourier analysis).

Hi Francesca, can you be more specific about what you want to do? If
you just want to subtract the raw data between runs, you can use fscalc.

I would like to be able to take the volume-to-surface transformation

You can use bbregister to compute the transformation for each run based
on the middle time point of that run (and assuming you've motion
corrected the run), then use mri_vol2surf to resample any data set
aligned with the middle time point to the subject's surface or the
fsaverage surface. You
You might need to smooth even more.

This is the polar angle map? What does it look like inflated? Do you

We have processed retinotopy data and piped the phase maps into

Thanks a lot!
I tried the registration with bbregister but unfortunately when I checked
the result the functional volume was very distant from the target.
Could I tried something else to improve the registration?
I typed:
bbregister --s subject --mov name_file.nii --reg register.dat --init-fsl
It was probably the initialization that failed. To test this, run
fslregister (very similar command line to bbregister). If that does not
look good, then it is an init problem. If these were acquired in the
same session, then you can try using --init-header. If you have spm
installed, you can

Not sure where you can find a verbose documentation, but you can figure
out by looking at the file read_surf.m in the ${FREESURFER_HOME}/matlab
