Hello,

 

I’m preparing to do resting state analyses and I’d like to use the Yeo 2011 network atlas for the cortical parcellations. Looking through the archive, I know that mri_surf2surf with the –sval-annot flag can be used to convert the fsaverage from the Yeo et al 2011 study to an individual subject space, but I noticed a caveat to this when I called mri_surf2surf –help. The caveat is on example 5: “this is not a substitute for running the cortical parcellation! The parcellations that it maps to the new subject may not be appropriate for that subject.”

 

Given this information, I’ve got a few questions:

 

1)      How accurate is the mapping using mri_surf2surf? That is, is it good for preliminary data, but not for the final analysis?

2)      How do you run the cortical parcellation using the Yeo 2011 atlas? [I know that mris_ca_train and mris_ca_label exist, but I’m unsure if they are the right commands to run when I’m not building my own atlas]

3)      If I do the cortical parcellations using the Yeo 2011 atlas, will the edits/labels I’ve done using the Desikan atlas remain accurate? This goes back to the second question, as I’m not sure where in the general processing stage I need to go.

 

Thank you!

 

Sincerely,

 

Emma Bailin
