Hi CONN team, 

I’m reporting results from a seed-to-voxel task-based functional connectivity analysis in CONN (not gPPI).

At the second-level (Patients > Controls, Right-Hand Draw condition), the results table lists t(42), uncorrected p, and FDR-corrected p, and the associated bar plot is labeled “Effect sizes".

1. What metric the “effect size” label refers to — are the bar values the mean Fisher Z correlation for each group, or some standardized statistic?

2. For the contrast itself (Patients > Controls), in addition to showing the bar plot, what is the most accurate way to report or compute an effect size in the manuscript? given that the displayed values in the bar plot are per-group for each cluster rather than per-contrast?

Thank you, 

Samah
