you won't need to rotate them. They are attached to the surface, so if
the surface is rotated, they will be too

If I want to rotate sucli pattern too if it is the same?

I guess you could rotate the surfaces, save them, then resample the
labels so that they get the new surface coords and sample them
into the volume, then onto the newly created surfaces. Not sure, we
haven't ever had to do anything like this.

Dear Bruce
I think the easiest way is to create all surfaces again but with corrected
and well aligned brain. The next step for me to create new labels from old
labels based on white surface (90 degree rotated) to new white surface.
But
how? Is there any way to do that? I mean like label2label or surf2surf if
two surfaces are the same but one of them only rotated?!

I don't see how anything would work if it was off by 90deg, but
I guess you should try it

Because I am using a result from a very old experiment
that done on wrong direction and the orig.mgz s are not
oriented according to
freesurfer template. I cannot creat white because all
results that I have (label files) are on white surface.
The only way that I think I need to
realign all surfaces and volume and apply that rotation on
my label files.

Dear Bruce
I have a data set which I can not create the white
surfaces because all of my results are according to white
surface. I would
like to know is
there any way to rotate all surfaces and volumes and
labels ... (everything) after finishing recon-all process.
like 90 degree
around X axis?
and apply this rotation to all data set?

Hi Rouhi
I don't really understand. Are you saying you
transformed the initial image before giving it to
recon-all? There is a
switch to
mris_register to initialize with the tal xform,
but we never use it as in pretty extensive tests it didn't
seem to help.
mris_register has a very large initial capture
range due to it's global search, so I would be surprised
if the initial
orientation
was the problem.

Dear Bruce
I think I found the problem. The problem came
from the original oriantation of T1 image and I think
mris_register could
not
find it itself during
the recon-all. I added to have initial alignment
to inflated and the problem solved.( mris_register -curve
-inflated
?h.sphere <template
target> ?h.sphere.reg ) I think it is very
important to add it to recon-all because if the user
doesn't know the real
oriantation it might make
such a problem.
Thanks for your quick response.

Dear Bruce
I am working on Freesurfer 2 caret meshes.
I am using FreeSurfer2CaretConvertAndRegisterClean.sh
from Van Essen lab
to
create caret
surfaces. when I look at my subjects'
surfaces I can see in flat map in caret some of subjects
sulci patterns are
really
distorted
and I think it is related to
sphere registration to fsaverage sphere. Beacsue the code
is using sphere.reg to create
all
surfaces.
for the subjects which I have less
distortion on sulci pattern I have good data (3 subjects)
but for the (9
subjects)
rest it seems
they have problem to register to fsaverage.
Is there any way that I can be sure that
sphere.reg properly created?
Thank you very much
