How to get the parcel name of FCMat_sorted?

[Weihankk]

Hi all,

I have obtain the FCMat_sorted (718*718) by LoadParcellatedDataInPython_Example.py scripts. In the script, the FCMat was ordered by cortex_subcortex_community_order.txt. I notice there is another file CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR_LabelKey.txt that store the parcel informations. I'm not sure the first row in FCMat_sorted (first parcel in FCMat_sorted) corresponds to 1 of column NETWORKSORTEDORDER or 1 of column INDEX in *LabelKey.txt file.

Maybe my description is a little confusing, in other words, the value in cortex_subcortex_community_order.txt correspond to which column in *LabelKey.txt file? The NETWORKSORTEDORDER or INDEX?

Sorry I am a beginner in fMRI, the description may not be clear, if you have any questions, please reply and I will add it in time.

Hi Weihan,
If you sort the parcels in CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR.dlabel.nii by the order provided in cortex_subcortex_community_order.txt, the new "index" of the sorted parcel is given in the NETWORKSORTEDORDER column of CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR_LabelKey.txt.

The values in cortex_subcortex_community_order.txt correspond to the INDEX column in CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR_LabelKey.txt.

So for example, parcel with INDEX 121 (Visual1-05_L-Ctx) has a NETWORKSORTEDORDER of 2, because it becomes parcel 2 after ordering by the list in cortex_subcortex_community_order.txt. Similarly in cortex_subcortex_community_order.txt, the first two values are 1 and 121, indicating that parcel with INDEX 1 from CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR_LabelKey.txt is still the first parcel after sorting, whereas parcel with INDEX 121 becomes the second parcel after sorting.

I hope that helps!

Hi jielisaji,
Thank you for your reply. Yes, I sorted the CortexSubcortex_ColeAnticevic_NetPartition_wSubcorGSR_parcels_LR_LabelKey.txt by NETWORKSORTEDORDER column, then the INDEX column is same as cortex_subcortex_community_order.txt.

Thanks for your help！
