RE: Coherence calculation
Hi Bryan,
One possible way to do this would be to use the option 'frequency-decomposition' in Setup.Conditions (or define your choice of frequency-bands manually there) to define frequency-specific conditions. After that, regular RRC first-level analyses will output correlation coefficient values between each pair of ROIs within each frequency band (so squaring these values will approximate magnitude-squared coherence metrics)

Hi,
I preprocessed and analyzed resting-state data within CONN and am now trying to figure out a method of determining the coherence (magnitude-squared coherence) of several of my ROIs. Is there a way of analyzing this within CONN?
Thanks!
