Gang,

Hi again. "I assume that you're interested in the cross-brain correlation[s] with the seed [at the subject level of the analysis]." Yes, I am interested in that.

"Not the scaling factors relative to the response at the [group level of the analysis]." I am interested in that, also. My ultimate question is: does the response during each arousal correlate with the cross-brain correlations with the seed?

"So, would it better to use the Fisher-transformed correlation values from each subject as input for population-level analysis? That way, your effect magnitude at the population level would be directly related to correlation." I am working on updating my analyses to use Fisher-transformed correlation values.

What are your thoughts on how I might calculate and show an effect size for the group level analysis? I would very much like to hear them.

Sincerely,

Dante
