Dear Anastasia,
Earlier I was posted an issue about BA44/pars triangular: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg23706.html
Because TRACULA also uses the cortical parcellation it may be important to handle this issue somehow. Is it handled in TRACULA analysis? Does it affect the result of WM-volumes?
Thank you for your answer, Gabor
