[ENH] Request for Inclusion of "KONG Networks" Option in Nilearn Function "nilearn.datasets.fetch_atlas_schaefer_2018()""

[PuneetDheer]

Is there an existing issue for this?

• I have searched the existing issues

Describe your proposed enhancement in detail.

I was hoping to find the KONG 7 or 17 Network atlas, as referenced in the following source:

[VERSION 3. Schaefer2018_<#ROIs>Parcels_Kong2022_17Networks_order]
https://github.com/ThomasYeoLab/CBIG/tree/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal.

However, it seems that this atlas is not available through the nilearn function, as indicated here: https://nilearn.github.io/dev/modules/generated/nilearn.datasets.fetch_atlas_schaefer_2018.html#nilearn.datasets.fetch_atlas_schaefer_2018.

The current functionality only allows for the use of the "yeo_networks" parameter.

I kindly request that you consider adding the KONG 7 or 17 network option, which could be labeled as "kong_networks," similar to the existing "yeo_networks" parameter.

Your consideration in this matter would be greatly appreciated.

Benefits to the change

The inclusion of the "kong_networks" option would enhance the utility of the network atlas by providing access to a broader range of networks, notably, the auditory and language networks/parcels, which are not currently available through the "yeo_networks" parameter.

For reference, you can view the language and auditory parcels here: https://github.com/ThomasYeoLab/CBIG/blob/master/stable_projects/brain_parcellation/Schaefer2018_LocalGlobal/Parcellations/MNI/freeview_lut/Schaefer2018_1000Parcels_Kong2022_17Networks_order.txt.

Your consideration of this valuable addition is sincerely appreciated.

Thx for the suggestion.
We already have Schaefer atlas available. https://nilearn.github.io/stable/modules/generated/nilearn.datasets.fetch_atlas_schaefer_2018.html
Isn't it enough ?
Best,

Hi bthirion

You are absolutely correct in noting that the "Schaefer atlas" is indeed available. However, it appears that there is no parameter option to select the KONG 7 or 17 network within this atlas. Instead, the atlas only allows the use of the "yeo_networks" parameter.

For your specific needs, I would like to direct your attention to an alternative option: VERSION 3. Schaefer2018_<#ROIs>Parcels_Kong2022_17Networks_order. This version of the Schaefer 2018 atlas provides the capability to access the "Language" and "Auditory" parcels, which are not available when using the "yeo_networks" parameter with the Schaefer atlas. You can find further information on this version on the provided GitHub link.

Additionally, I would like to draw your attention to the image link here, which displays the language and auditory parcels in the Schaefer2018_<#ROIs>Parcels_Kong2022_17Networks_order.

This Kong network option indeed offers access to the specific "Language" and "Auditory" parcels that are not available when using the "yeo_networks" parameter with the Schaefer atlas. For your convenience, you can find more details in the links provided.

Best,

[PuneetDheer]

Could you please look into it?

We will discuss this in an upcoming coredev meeting. Best,

Was discussed at the last core dev meeting and decided that this is out of scope for Nilearn:

We have updated the documentation to make our policy regarding adding new atlases more obvious (note this is not a change in policy just trying to make it easier to point to) and also pointing to other projects that may accept atlas contribution:
