Hi Paul,
No, they don't give the exact same results (although they are not very different), so the question is: shouldn't the results be exactly the same?
The settings to each function are equivalent - detrending, bandpass, removal of orts, etc. The only difference is that in the first case I use 3dTProject to first remove the nuisance time series and then pass the (cleaned) time series to 3dRSFC, whereas in the second case the nuisance time series are removed directly with 3dRSFC.
But otherwise the two approaches should give me identical results, shouldn't they?
Best regards,
Sam
