RE: Questions about Harvard-Oxford Subcortical parcellation used for Conn toolbox
Just adding to Daniel's reply:

The atlas.info file will give you the details of how the atlas file in Conn was created by merging ROIs across Harvard-Oxford cortical and subcortical atlases and the cerebellar parcellations from the AAL atlas. The text file also mentions how discrepancies are resolved and the relevant references.

The atlas.txt file is a lookup file. Each line in this text file refers to a region in the atlas.nii file. For example, line 1 FP r (Frontal Pole right) corresponds to region number 1 in the NIfTI file (i.e. the atlas.nii file with intensity=1 is the right frontal pole).

I am not sure if this will answer your question or you already knew that. If you go to your conn folder, then /rois/, there you will find the files atlas.txt and atlas.info that may clarify some of these issues.
Hope this helps.
