How to reconstruct tracts within a specific cortical region?

[Go Cram]

Hi Frank,

I want to reconstruct tracts within a specific cortical region, ie. the seed region and endpoint region are both the specific cortical region.
I have tried setting “specific mask” >> Seed and “specific mask” >> ROI
Or “specific mask” >> Seed and “specific mask” >> End
Or  “specific mask” >> Seed and double “specific mask” >> ROI

But none of the above get a good result.

So what should I do?

Thanks in advance for any advice,
Panshi

Thank you for this guidance, Frank.

But I would like to reconstruct the tracts that sent out from a specific cortical region and also end in the region, diagram:

And I set the regions as the above diagram

However, the tracts are is not as I expected:

Do you have any advice on tracking fibers like the diagram?

Thanks!
