Hi Sherryse
you only need to register the anatomicals to the funtionals once, then
sample the functional data onto the surface using mri_vol2surf. This will
create a surface overlay that can be visualized on any of the surfaces
for that subject (e.g. lh.white, lh.pial, lh.inflated)

Hi FreeSurfer Team,
Please help out a FreeSurfer newbie! We are having an issue with mapping
our functional data onto the inflated brain. When we finish the mapping, it
seems that much of the data is showing up in white-matter space, and
therefore, cannot be seen on the external surface of the brain. We later
discovered that we were likely using the wrong registration matrix. However,
it doesn’t seem like the one we are supposed to use is being produced during
recon-all. I am new to FreeSurfer and would greatly appreciate some
assistance!
To provide you with more detail.
Problem: When we run the command line below, and then open the folder
experiment.feat/reg/freesurfer, there is no
anat2exf.register.dat file. However, there is a file called:
anat2exf.register.dat.init.
Command Line: Reg-feat2anat -feat OurFeatDirectory.feat -subject P143
Terminal Output: There is no terminal output. No error of any kind.
Log File: Attached.
Thanks,
Sherryse
P.S. We submitted this issue previously but were not getting a response, so
we tried again in case our thread wasn’t working properly.
