Hi Bruce,

Following up on your comment below, if I am using 'lh.thickness.fwhm10.fsaverage.mgh' for my thickness values, do I read in the lh.aparc.annot file in the subjects directory? I tried doing this for one of my participants, and the vector of thickness values has 163842 columns, while my aparc file has 116407. Or should I be reading in the lh.aparc.annot from fsaverage?

Kind regards,

Hi Bronwyn

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

cheers

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?
