[color=#000000]Hi Ruth,[/color]
[color=#000000]Currently there is a separate script (part of the CONN package but not yet integrated into CONN's gui) that would allow you to perform these sort of within- and between- network analyses. To use it you should:[/color]
[color=#000000]1) in CONN's gui [i]second-level results [/i]tab, define there the specific model that you would like to test (i.e. select the subject-effects and associated between-subjects contrast, and the desired conditions and associated between-conditions contrast)[/color]
[color=#000000]2) then in Matlab command line type[/color]
[color=#000000] conn_withinbetweenROItest;[/color]
That will prompt you to select two networks (e.g. select the 5 ROIs that belong to each of your first two networks) and then it will output a file containing the within- and between- network connectivities (averaged across all the ROIs within each network) for each subject, as well as the statistics associated with your selected second-level model again for the within- and between- network connectivity values.
Let me know if this is what you had in mind.

I am looking into second level ROI-to-ROI analyses and am hoping to calculate average within- and between- network correlations for each of the networks of ROIs in two separate RSFC runs.
For example, if I had 3 networks, each with 5 ROIs, I would be trying to do two things:
1) to obtain an average within-network correlation during run1 and during run2 for each of the three networks (specifically I am looking for a single average correlation among the 5 ROIs in network 1 at run1 and then their average correlation at run 3--and then I would do the same calculation for the other two networks separately).
2) to obtain between network average correlations for each network (specifically I am looking for a single average correlation for 5 ROIs in network 1 with the 10 ROIs comprising networks 2 and 3, calculating this at run1 and then again at run 3--and tthen I would do the same calculation for the other two networks separately).
Is this possible to do in CONN, and, if so, how might I go about obtaining these measures?
Thank you so much for such a great program and for any help on this question you can give me!
