Dear all, We are trying to extract a cerebral white matter mask from the Freesurfer output. We are currently using the aparc+aseg file in order to do this, however we realized that the white matter mask (taken by choosing the voxels with values equal to 2 and 41) doesn't correspond exactly to the white matter we would like to have, which rather would follow the WM boundary obtained with the surface processing. Is there a way to get a more accurate mask that corresponds to these boundaries? Also, is there a description of the file format that the surface files are written in?
Thank you, Antonio _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
