Yes. The 2nd would dilate in all dimensions, but you would only keep those voxels that were in WM. but the 1st is definitely cleaner On 12/18/19 2:52 PM, Corinna Bauer wrote: > > External Email - Use Caution > > Ok thanks! The first option sounds like it might provide a cleaner > result,

External Email - Use Caution Ok thanks! The first option sounds like it might provide a cleaner result, since the second would dilate in all dimensions. I'll let you know if I run into any trouble with it. Thanks again, Corinna On Wed, Dec 18, 2019 at 2:45 PM Greve, Douglas N.,

off the top of my head I can think of a couple of ways 1. replicate the wmparc.mgz stream. For this you will need to create an annotation from your GM ROIs by combining them into a ssegmenation, then using mri_vol2surf to create a surface-based segmentation, then using mris_seg2annot, then use m

External Email - Use Caution Hi Doug, Yes, I have GM ROIs in CVS space and I'd like to create a corresponding WM ROI for each of them that extends 2-3 voxels into the WM. Would it be possible to create something akin to wmparc.mgz with these ROIs? Corinna On Wed, Dec 18, 2019 at

Hi Corinna, if I understand correctly, you basically have cortical GM ROIs in CVS space and you want to create an ROI of the adjacent WM. Is that right? How far do you want to extend the ROI  into WM? Do you want to do something like a wmparc.mgz? doug On 12/18/19 9:55 AM, Corinna Bauer wrote:
