A question about file names of the result

Dear Dr. Yan and DPARSF-users:

After I finished the processing steps in DPARSFA, I found that there are 3 different ROI signal files with ".mat" in the result folder. You can see them in file attachments.

I wonder the difference among them and, if I want to use the time courses of ROIs to make correlation analysis, then which file should I use?

Thank you for considering my request!

Best wishes!
