That is on if the outputs of the default freesurfer
analysis pipeline. Did you run recon-all --all yet?
Peace,
Matt.

Subject: [FSL] brainmask.mgz - how
to produce for Freeesurfer ?
Dear FSL-Freesurfer experts,
I would like to use Freesurfer to segment functional time series images.
To do so, first I have to register example_func.nii to anatamical using
routine:
reg-feat2anat
however I can't run it, since I don't have this mask file, the complain is as
follows:
FeatDir is 1_Left+.feat
template volume is 1_Left+.feat/example_func.nii.gz
ERROR: cannot
find brainmask for test
How can I produce this mask? I thought that following the tutorial on FLIRT
will help me , but the mask produced by FLIRT:
------------------
http://www.fmrib.ox.ac.uk/fslcourse/lectures/practicals/reg/index.html:
Standard-space
masking - a useful application
Now let's use a saved FLIRT transform to mask out the ventricles, cerebellum
and brain stem in example_func,
using a crude standard-space mask which excludes those regions.
The registration from example_func
to the standard-space template has already been done and is saved as exfunc2std.mat.
We want to take this matrix and transform a standard-space mask to the
functional space.
---------------------
The description above sounds like the relevant procedure, but did not
change anything
Can anybody please advice me on this matter?
