I think he wants to do a correlation of an ROI of the hippocampus. There you would benefit from doing as Tim suggests, but then using wb_command -cifti-average-roi-correlation

You could also extract the labels from the Pipelines/global/templates/91282_Greyordinates/Atlas_ROIs.2.nii.gz file with -volume-label-to-roi.

May I know which atlas file is the right one to extract hippocampus ROI ? Thank you very much!
