Hi Beth,
Allow me to chime in here: I would discourage you to rely on the fiducial and
landmark locations as provided. These I have clicked in the 1mm anaromical
images
If you are talking about resampling the low-resolution data onto the higher
resolution mesh, yes, you can resample either direction (uses the same
files, in fact, just reverse them). You will need the spheres used to
downsample the surface in the first place. Look at

Hi,
I included Eric here who also is an author of PySurfer which we
Back on this other question, wb_command indeed does not do decimation of
the remove vertices from existing topology variety. The usual way to do
surface downsampling with wb_command is to generate a new sphere with the
desired number of vertices (and highly regular topology/spacing), and then
Hi Denis,
Indeed the meshes’ vertices are indeed already registered in surface space,
i.e. to the fsaverage, and are obtained from the 32k meshes provided in the
structural processing package. However, we used wb_command for the subsampling,
which as far as I know is in fact doing a
I just downloaded the MEG data from the 500 Subjects + MEG2 Data Release. I
see from the documentation that the MEG data should include a head shape file.
This is not present in my downloaded set. Where can I get these?
Thanks,

I was wondering wheather the transforms would be suitable for mapping the
freesurfer surface coordinates to the helmet space.
If this step would work, the transforms and the coreg would be usable with
other software such as for example the MNE suite.
We could then write a routine that skips the
Dear Beth,
the head shape files are not provided with the data.
The reason for this is that headshape digitization includes points
around the nose, the eyes, the forehead and the entire head. This means
that this information could lead to identification of a subjects identity.
This is also the
