ROI-wise Functional Connectivity in REST

Submitted by nertman on
 Hi, I just finished running a functional connectivity analysis using the REST toolbox. I am looking at the FC between 2 regions so I entered those as ROIs and chose ROI-wise analysis.

The output is a series of txt files and I am wondering what exactly the numbers in the txt files represent? I am guessing that:
  • FCMap_*.txt is the Pearson's correlation between the time course of the two selected ROIs? 
  • ROI_FCMap_*.txt is the Pearson's correlation between the time course of each ROI and other voxels in the brain (not sure which)?
  • zFCMap_*.txt is a z-transformed Pearson's correlation between the time course of the two selected ROIs?
Thanks for any help!
