Dear GZ,

The atlas lives in its own space, and it is hard to register to MNI because it only describes probabilities, and not image intensities. But you could try registering your subjects to MNI, propagating the thalamic segmentations, and analyzing the data in that coordinate frame.

Cheers,

Subject: [Freesurfer] The thalamic atlas in MNI space

 

        External Email - Use Caution        

Dear experts

 

 

I am performing a fMRI analysis about the thalamus. I would like to see the overlap of my thalamic ROI with the atlas derived in 'A probabilistic atlas of the human thalamic nuclei combining ex vivo MRI and histology' (Iglesias, NeuroImage, 2018). Is there a version of this atlas in the MNI space? I found the 'ThalamicNuclei' folder in FreeSurfer but it seems not an atlas in the MNI space. I am new in FreeSurfer. Could you please give me some suggestions?

 

Thanks for your time.

 

Best,

Guangyuan Zou
