That's true, but the sample correlation coefficient is asymptotically normal. I
agree with Benjamin based on some

Ah that makes sense, thanks! The effect of the z transformation is quite subtle

I would probably z transform before averaging across runs, so that you are
averaging something with at least an approximately gaussian distribution.

Hi Ely,
We don’t have a function like this yet, but have been discussing making one.

Hi everyone,
I'm running some connectivity analyses following the procedure outlined in this
thread
https://www.mail-archive.com/hcp-users@humanconnectome.org/msg04403.html. Since
my ROIs are fairly small, I'd like to calculate the correlation between the
mean unsmoothed timeseries of each
