Seed-based Functional Connectivity within a Network Mask in CONN

Dear all,


I think I've found a way to calculate functional connectivity using seed-based analysis within a network mask in CONN, and would like to know if you can valide my approach described below:


1.) I imported a mask (based on the ROIs implemented in CONN, for example, for the DMN) as an ROI in SETUP.ROIs.
2.) Then, I proceeded with preprocessing and denoising the data.
3.) Next, I defined a seed-based analysis with this imported mask as the ROI/seed of this analysis in the ANALYSES (1st-level) tab.
4.) In the RESULTS (2nd-level) tab, I opened the second level analysis results window and clicked on "import values". In the newly opened window, I selected the option "others clusters of interest or ROIs (select exported mask/ROI file)" and selected my network mask (the same one I originally imported as an ROI in SETUP.ROIs) again. 
5.) Now, I have one functional connectivity value for each person in SETUP.Covariates (2nd-level), which I can extract for further analysis outside of CONN/SPM.


Can you confirm my procedure described above as a method for extracting functional connectivity values within a network mask?


Many thanks and best,
Max
