[FieldTrip] using freesurfer cortical atlases

[Luke Bloy]

Thanks this is will be much faster than my brute force method.

Hi Luke,

 

If you read in the *.fif sourcemodel using ft_read_headshape, it contains a
field called 'orig'. The subfield orig.inuse links the vertices in the high
resolution tessellation to the vertices in the sourcemodel.

Hi,

 

I'm using cortically constrained mne to look at some auditory ERfs. I'm
roughly following this tutorial,
http://fieldtrip.fcdonders.nl/tutorial/minimumnormestimate. What I would
like to do is to impart some anatomical information onto my findings. I can
load the desikan atlas created by freesurfer using ft_read_atlas, but the
points I get from this don't match the points I get from the sourcespace
that I created with mne_setup_source -iso -6.

 

Does anyone have any experience with this?

 

Thanks,

Luke
