Hi Anita, I think this discrepancy may have occurred when I switched the order of L and R hemisphere parcels during a version update to conform with the Glasser parcellation, but overlooked the Matlab file. I will look into it tonight. Thank you for bringing this to my attention!

Thanks for the response! Yes, please let me know what the correct mapping from Glasser parcellation to Cole-Anticevic is, as I am using it for some current analysis and would like to cite your paper.

Hi Anita, I took a look at your GlasserToColeAnticevicMapping.txt. Did you perform a sorting of the indices in your "CAB Network" column before appending them to the Parcel column? If you open cortex_parcel_network_assignments.mat, it should tell you the network that each Glasser parcel belongs to, in the original left 180, then right 180 parcel order (following the Parcel Index column in the table on Pg 81 of the supplement file you linked). For example, the first 5 values in cortex_parcel_network_assignments.mat values are:
1
2
2
2
2
Indicating that the 1st Glasser parcel (V1 in Pg 81 of the Glasser supplement you cited) belongs to Network 1 (Visual1), and the next four parcels (MST, V6, V2, V3) belong to Network 2 (Visual2). Similarly, indices 181-185 of cortex_parcel_network_assignments.mat are:
1
2
2
2
2
Because these parcels in the right hemisphere are assigned to the same networks.
If you simply append the vector in cortex_parcel_network_assignments.mat to a vector 1-360 you should have the corresponding parcel/network pairing. I hope this addresses your question!

I think I may have figured out where the confusion stemmed from. Under "Included Files", I interpreted cortex_community_order.mat as the order in which we needed to reorder the 360 Glasser parcels in to then use cortex_parcel_network_assignments.mat (i.e. Glasser parcel 1, 7, 8, 9, etc) to match up the reordered parcels to their corresponding Cole-Anticevic networks (i.e. 1, 2, 2, etc.) . Is cortex_community_order.mat not used for Glasser parcel -> Cole-Anticevic network pairing then?
Just to clarify, if we keep the 360 Glasser parcels in their original order (all 180 left regions first, then 180 right regions), we can simply map one-to-one with the indices in cortex_parcel_network_assignments.mat, correct?
from coleanticevicnetpartition.
Ordering by cortex_community_order.mat sorts the 360 parcels in "network order" (i.e. all VIS1 parcels, then VIS2, then SMM etc.). I apologize if this wasn't clear -- I'll update the description of the file in README to hopefully clarify this. The cortical parcels in CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR.dlabel.nii is by default in Glasser parcel order, so you are correct, they match 1-1 with the indices in cortex_parcel_network_assignments.mat.

Thank you for the clarification, I appreciate it. Makes sense now.
