That is what I would do. The FS WM volumes are computed using the surface, so it will be more accurate (and probably a little bigger)

Dear SAMSEG developers,
Is there an easy way/specific function to compute the total volumes (GM, WM and Total Brain) after the cross sectional processing pipeline has been run?
I currently add the volumes specified here: MorphometryStats - Free Surfer Wiki (harvard.edu) https://secure-web.cisco.com/1TiZSqlkmJdSG6YomLyN1O5wCUsd9cdQzzIoKCQYS9WpviPI49_lorZ_PTx-cok1PIeuP8aWJ0IV6NMrcGfHODM2PLpH9RCWg-ln0Jg3_V6zwsh77nVZB4eIAR3Y-sri82P9wc_X4NwGgnapiZ_giZMZuqHSwm3ql2xGpURyF3CTBTmybLP1w9Cv7SbWp2TZhZkZnRB9yYZHo-e9S5TPVgg_igr4Am5G0FC_cGgwpO0coHVaAsMKqmpERVazbMNtYaLa3U6l0NChbwkbKfwL0wA/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FMorphometryStats
However, adding the WM volumes *(**lhCerebralWhiteMatter + rhCerebralWhiteMatter + WM hypointensities) results in lower volumesthan the volumes found with FreeSurfer.*
