Hi, 

I am trying to export the beta values of ROI - ROI analysis so I can include them in a cluster analysis. Specifically I am looking to extract single subject beta values fo the the AC to all other atlas ROIs (excluding brainstem and cerebellum). 

I'm not trying to determine significance or group differences, just need to extract the uncorrected betas from all subjects so i can inlcude it with other data. Is there a way to do this within Conn? Otherwise I might have to find a way outside of Conn, which could be more difficult and time consuming. 

Best, 

Eric

Hi Eric,

If you have run a RRC analysis in CONN (e.g. named RRC_01) then you can find the actual connectivity matrices for each subject in the files named [YOURCONNPROJECT]/results/firstlevel/RRC_01/resultsROI_Subject###_Condition###.mat (see the file _list_conditions.txt in that same directory to associate condition names to condition numbers).

Within those files, the variable Z will contain the connectivity values for each pair of ROIs (the nature of these connectivity values will vary depending on your choice of connectivity metric for the RRC_01 analyses; e.g. they will be Fisher-transformed correlation coefficients if you have selected correlation measures, or regressor coefficients if you have selected regression measures)

Hope this helps

Alfonso
