Hi all,

I am trying to do some dynamic analysis on my resting data, I extract the mean value of my ROIs in different time window and then calculate their Correlation with 1dCorrelate like this:
3dmaskave -mask $subj.r$run.PCC+tlrc. -q errts.$subj.r$run.e2t+tlrc.'[0-49]' > r$run.dy1.PCC.1D
3dmaskave -mask $subj.r$run.LmPFC+tlrc. -q errts.$subj.r$run.e2t+tlrc.'[0-49]' > r$run.dy1.LmPFC.1D
1dCorrelate -p r$run.dy1.PCC.1D r$run.dy1.LmPFC.1D
The ROIs I chosen are widely be defined as part of the default-mode network so they should be highly positive correlate with each other, but the output is zero, I wonder if I use this script wrong?

Best regards,
Sue
