Hi Alfredo,
the stats files are summary measures over the ROIs, whereas QDEC lets you make statistical maps and obtain p-values for every point in the cortex.

Dear Freesurfers,
this question may be naive - I somewhat new to freesurfer. What is the difference between analyzing data with QDEC or just using aparc-aseg.txt values in other statistical program (besides being able to "visualize" the results).
Many thanks Alfredo Damasceno
