Dear users

I have some maps computed on the 2018 Schaefer 100-regions volumetric parcel that I want to map on the Yeo 7networks 100 regions surface parcel.

- For the volumetric, I have this LUT

https://github.com/netneurolab/hansen_receptors/blob/main/data/schaefer/coordinates/Schaefer_100_centres.txt

with labels like "L_Schaefer_Area_1"

- for the surface I have the lut that can be downloaded from here

https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation_Yeo2011

with labels like "7networks_LH_Default_IPL_1"

I hoped that the labels were ordered in the same way, but after some plotting I'm sure it's not the case. Do you know any way I can map one into the other? Thank you

Hi Simone,

Please refer to the parcel labels at https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/MNI/freeview_lut/Schaefer2018_100Parcels_7Networks_order.txt

And compare your labeling with the files we released at https://github.com/ThomasYeoLab/CBIG/tree/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/MNI

Let me know if you still find them mismatched. Thank you.

Best Regards,

XUE Aihuiping

Hi Aihuiping

I still find mismatches between label names in

https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/MNI/freeview_lut/Schaefer2018_100Parcels_7Networks_order.txt

and in

https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Yan2023_homotopic/parcellations/FreeSurfer/fsaverage/label/yeo7/lh.100Parcels_Yeo2011_7Networks.annot

I wanted to understand whether a mapping is possible between Yeo's 100 regions 7 network parcel and Schaefer 2018 MNI 100 regions 7 network parcel.

In the two parcels, names are clearly different, for example in Schaefer there are more "Vis" labels, 9 for left and 8 for right hemi.

Here are Yeo's parcels

HI Simone,

Do you mean "Yeo" or "Yan"?

I am not aware of a Yeo 100-region parcellation.

On the other hand, the labels of the Yan-400-region and Schaefer-400-region parcellations will be different because they are different parcellations.

Thanks,

Thomas

Hi

At this link here

https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Yan2023_homotopic/parcellations/FreeSurfer/fsaverage/label/yeo7/lh.100Parcels_Yeo2011_7Networks.annot

the name is quite explicit and refers to a "Yeo 100 regions parcellation".

Also, the surface-based parcellation I obtained was downloaded from here

https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation_Yeo2011

where they explicitly state this is "Yeo", and provide a 100-regions, 200-regions, 400-regions and so on versions

Thank you

Simone Cauzzo

Hi Simone,

Just to clarify, the link you referenced (https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Yan2023_homotopic/parcellations/FreeSurfer/fsaverage/label/yeo7/lh.100Parcels_Yeo2011_7Networks.annot) refers to the 100-region Yan2023 parcellation, with each parcel assigned to one of seven yeo2011 networks. Notice the file is under the "Yan2023_homotopic" directory.

Previously, Aihuiping pointed you to the following links:

Please refer to the parcel labels at https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/MNI/freeview_lut/Schaefer2018_100Parcels_7Networks_order.txt

And compare your labeling with the files we released at https://github.com/ThomasYeoLab/CBIG/tree/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/MNI

Can I clarify that they are not what you want? Please kindly elaborate a bit more. Thanks!

Regards,

Thomas

Oh, this makes things clearer.

Thank you both for the help, I understand that there is no mapping between my regions (that are Yan's 100 regions with Yeo's relabelling) and Schaefer's 100 regions.
