second-level analysis in Conn
> (Hi Alfonso,
I followed your instructions, thank you very much. I am currently looking at the third option you listed - " select 'Group1', 'Group2', 'Group3', 'Scores1', 'Scores2', 'Scores3', and enter a contrast [0 0 0 1 -1 0; 0 0 0 0 1 -1] to look at any differences between your groups in their association between symptom scores and connectivity". I have also selected 3 ROIs from the �seed/source� section. I�m new to Conn and not sure how/where to go to read the results. The table that pops out titled �connectivity values�, when all variables are selected, shows connectivity of each ROI to the one selected in the �Analysis results� for each group and it also lists the same information for the symptoms scores. In other words, it is treating the symptom scores for each group as additional independent groups even though these are within group variables. I�m looking for the correlation between the symptom score and connectivity within each group and whether it differs significantly across the groups. Where can I find/produce this information? I would deeply appreciate your help. Many thanks.
Best,
Diana.
