Hi Alfonso,

I'm very new to CONN (only did some exploratory seed-based connectivity analyses between 2 groups), but now I want to use the script conn_withinbetweenROItest (with ROIs of the Default Mode network) in CONN (version 20.b).

For this, I defined my between-subjects contrast etc. in the results (second-level) tab and typed conn_withinbetweenROItest in the MATLAB command line. But after that, the following error was displayed:

Reference to non-existent field 'roiselected2'.
Error in conn_withinbetweenROItest (line 16)
ntargets=CONN_x.Results.xX.roiselected2;  %selected target ROIs
(indexes to names below)

I need to select my ROIs again or to name my selected ROIs, but how can I name or select my ROIs? 


Thank you for your help!
