SPM marsbar problem

Submitted by aynur.k on

Dear Experts,

I would like to extract the ROIs of DMN using the  coordinates of one of the related studies (i.e. Yeo et all or Van dijk et al).

My question is what determines the sphere radius?

Could I increase the radius to include as much voxels as possible without merging into neighboring regions?

Moreover, it would be great if you could help me with any alternatives.

Thank you!

If you are using Yeo networks, you don't need to define sphere ROIs. Just extract the DMN signals (index 7), using DPABI->Utilities->ROI signal extractor.



Dear Chao-Gan

I would also like to use the Yeo networks to extract signal, could you elaborate a little further, you wrote that "Just extract the DMN signals (index 7)", what do you mean by that? When I chose the option "define ROI", I can chose between a number of atlases but not the Yeo atlas?

Thanks a lot!
