you can use mri_label2vol to sample the aparc+aseg.mgz into the functional space, then run mri_segstats on it to give the number of functional voxels in each label. Or you can just look at the volume of each label and divide by the volume of your functional voxel. [EMAIL PROTECTED] wrote: De

[Freesurfer] Number of voxels that intersect with inflated brain surface

2007-08-07 Thread raij
Dear FreeSurfers, Is there a way to estimate the number of fMRI voxels that intersect with the FreeSurfer anatomical inflated surface space? -"- for a given surface label? We need this as N for calculations of statistical significances (to correct for the oversampling of the orginal 3D voxel spac
