Tractography atlas

1

Dear Brainstorm Team,
is there a tractography atlas aligned to the ICBM152 template that I could import in Brainstorm? I tried to import the HCP842_tractography atlas (https://brain.labsolver.org/hcp_trk_atlas.html), but I am still trying to find a way to make it work. While I keep trying to find a way to import the HCP842_tractography atlas successfully, I was wandering if there are other available options.
My final goal is to lable the SEEG contacts in the white matter (contacts coordinates are in MNI).

Thanks
Francesca Talami

May be the atlas uploaded on Brainstorm tutorial could help:

it is aligned with ICBM152, as you can read on the tutorial:

Thank you very much. I am already using the .trk template, although what I am looking for is an anatomical atlas for anatomical labelling. Something like what is described here (Section 9) https://neuroimage.usc.edu/brainstorm/Tutorials/ECoG#Anatomical_labelling

I have been trying to import this atlas
HCP842_tractography.nii.gz (1.7 MB)

Do you have any suggestions?

Hi Francesca,

To use anatomical labelling, first it's necessary to add you atlas in Brainstorm. However, the file you shared is a multi-volume file (with 80 volumes), and atlas volume that Brainstorm expect that:

"Each parcellation is a volume of integers where each value represents an anatomical label, and registered to an MNI space."

Best,

Thank you.

I manage to create a single volume file of the atlas and import it in Brainstorm and it looks good.

Here it is the file, in case somebody else needs it:
