Re: [Freesurfer] Extracting individual vertex values for surfaces mapped to fsaverage

Hi Bronwyn

you can use read_annotation.m to read in the parcellation that you want and go from there.

Dear mailing list,

For each of the subjects in our study, we would like to extract the thickness values at each vertex for the surface that has been mapped to fsaverage (so that the number of vertices is identical for all of our subjects). After changing to a specific participants "surf" directory and starting matlab, could I use the following command and file to extract the data I want?:

[thick, fnum] = read_curv('lh.thickness.fwhm10.fsaverage.mgh')

Also, how do I then determine the annotation associated with each vertex for each subject?
