Dear conn users, Dear Alfonso,

when performing a functional connectivity (ROI-to-ROI) comparison group in the second-level analysis (for example to compare the connectivity results of patients vs. controls), does the conn tool box take into account an absence of connectivity in this analysis?

For example, is it possible that it shows a result for the group patient connectivity = 0 vs. of the group control connectivity = 0.5?

Or, is that the conn tool box only shows the between-groups differences in connectivity for existing connection in both groups (but that differ in terms of strength, not in terms of presence vs. absence)?

Thank you for your attention to these matters.
