Dear freesurfer experts:
I have been using matlab to analyze a retinotopic dataset.
However, the 3D volumes are not in standardized space (and I wish to display
multiple maps from different subjects on one surface).
Although the initial segmentations were done in freesurfer, my question is:
Is
Hi Jason
why not map them all to fsaverage and display them on a common surface?
cheers

Hi Doug,
I am now at the bbregister stage ... I ran this but it is not clear to me where
the output is? I don't see an output flag ...
Can you tell me where to look for my output?
Almost there!
Many thanks, Jason.

Hi Bruce,
Here it is:
bbregister --s bert --mov /Applications/freesurfer/subjects/bert/mri/f_RH.mgz
--reg register.dat --bold --init-header

Dear freesurfer experts:
I noticed that there are two 'vol' fields when I use MRIread.
1) mri.vol
2) mri.analyzehdr.vol
My question is:
I have two arrays, one with 3D coordinates and a second 1 dimensional array
with corresponding phase values.
Which 'vol' field do I put the 3D coordinates i
Dear freesurfer experts,
I have used the mri.vol and mri.analyzehdr.vol fields to encode my coordinates
and phase values using MRIread and MRIwrite (f_LH12.mgz).
I then brought these data into freesurfer using the following:
bbregister --s fsaverage --mov
/Applications/freesurfer/subjects/fsav
Thank you for your advice Doug.
Best wishes,
-jason.

Dear freesurfer experts:
I am new to fs-fast and I am currently running sfa-sess on some retinotopy data
and I think the main error is "cannot determine format of 005/f"
I read in a previous post related to retinotopy that you need to add the full
path to the .nii files and then it will work.
Dear freesurfer experts:
Recon-all is running in a few seconds (obvious error).
I am getting the following screen output on Linux, when I run recon-all:

arlene -force
INFO: /usr/local/freesurfer/subjects/arlene exists
Thanks. It's working now. J

I'm having a problem I've seen posts about in the archive, but have not been
able to see the solution to it.
If I start tksurfer bert rh pial (as the example says), the display only shows
a small fraction of the brain and nothing more. I've tried some of the
