Number 11 afni proc Freesurfer White Matter Mask

Hi Rick,

I just saw in the afni proc py note that the brain stem was incorrectly included in the white matter mask. I actually just noticed I ran some data using number 16 in the white matter mask. I am guessing I should rerun these subjects as including the brain stem will throw off the accuracy of the regression?



Hi Emily,

Assuming the brain stem is indeed included, yes, it would
be prudent to re-run the analysis. Sorry about that! We
will be making some macros to help with this in the future,
which would enable a command like:

3dbucket -prefix SUBJ_WM.nii aparc+aseg.nii’<AFNI_FS_WM>’

That label does not yet exist though.
