Dear FS experts:

    I conducted recon-all analysis on my own subjects, and found that there are several kinds of thickness files, such as the lh.thickness file and lh.thickness.fsaverage file. By using MATLAB scripts implemented in FS, different numbers of vertex were found between the two files. What I am thinking is that the lh.thickness file is the individual thickness map (It has not been transformed into fsaverage space), while the lh.thickness.fsaverage.mgh is the thickness map in fsaverage space. Is that correct?

Best,

Zhiliang
