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?

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

External Email - Use CautionHello all,
I have a series of functionally-defined ROI volumes (.nii format) that I'd like to project into the white matter to then be used for tractography.
So far the vols have been brought from cvs_avg35 space into subject space from using mri_vol2vol and the corresponding m3z file. This was followed by mri_vol2vol using the registration from bbregister to get the functional regions into diffusion space.
I have done this for the ROIs in their original GM volume, but would now like to also have corresponding WM volumes for tractography.
What is the best way to go about doing this?
Thanks,
Corinna
