How to map ROI indices to names in parcelExpression?

[Mannyari]

Hi,

Thank you very much for this work!

I'm trying to work with the processed data available here: https://figshare.com/articles/dataset/AHBAdata/6852911. However, I'm having trouble understanding how to retrieve the ROI names from the parcelExpression field in the ROIxGene_aparcaseg_RNAseq.mat file. I only see increasing numbers in the first column, which I believe correspond to the ROIs.
It seems to me that the Desikan-Killiany atlas was used. I tried taking a look at the lh.aparc.annot file, but I noticed that there are 36 parcellations (including corpus callosum and unknown) instead of the expected 34, and some of the numeric labels are duplicated.

Could you help me clarify this?

Thank you so much!

Sorry, the region labelling wasn't clear. Please find the labels for 34 cortical regions in the left hemisphere attached.

There is also an option to use an open-source toolbox incorporating our data processing steps called abagen, please see the associated paper. This toolbox provides a reproducible way to process AHBA data and allows the use of a chosen brain parcellation.

Hope that helps.
