Hi,

My question is:

Is there a way to create a WM ROI based on 2 or more GM regions, e.g., if I use labels from the Desikan atlas like ctx-lh-posteriorcingulate AND ctx-lh-medialorbitofrontal and want to see the tracts that connect these two and then use it as an WM ROI.

I want to be able to define my GM regions based on brain networks (e.g., DMN) and get WM tracts that connect these regions within the DMN.

Hope this makes sense.

Best,
Omar
