Hi Alfonso and NITRC users,

I have a fairly nuanced question about the QA process that I've yet to find guidance on. I completed a QA report and confirmed that each of my main QC-FC association measures (MeanMotion, PVS, and Invalid Scans) each pass the recommended 95% threshold. However, the combined measures report below threshold at 93.8%. Is it recommended that both the individual and combined QC-FC associations meet the 95% or the individual measures sufficient. The subject-level QC measures do not show any extreme outliers >1.5 IQR for any of the substantial measures (invalid scans, PVS, mean motion, DOF). I have tried increasing the WM and CSF parameters to 15 parameters from 5 which results in the combined QC-FC measures to meet the threshold, however I'm not really sure if this is necessary or might remove important signal from dataset. I haven't really found any answers addressing this particular scenario, and I'm not sure why the combined QC-FC would be below the recommended threshold if the individual measures passed. Any guidance would be most helpful! 

Best,

Joe
