RE: How do I use the -faceMask option? (or, how to fix re-ears clipping into brain)

Jonathan,


The direct answer to your question is that you want to edit MCALT_FaceMask.nii, also in the .zip file.


Another possible workaround could be to use the TIVTolerance options and set them a little larger, but you need to QC the results carefully to make sure you don't start to retain too much of the eyebrow ridge and render the results not-really-deidentified.


The "long answer" is that this probably stems from your population. We have only tested this on adults 30+.  How young are these "kids"? Developing support for pediatric populations (with the needed extensive validation) is in our eventual roadmap, but for the current versions it would be "off label" and "at your own risk". Our project is funded by the National Institute on Aging, so it has not been a top priority.
