Hi everyone, I need your help/suggestion for the correlation analysis in NBS. I created my connectivity matrices for a patient sample (n 48) and I want to run a correlation analysis to check the association between internodal functional connectivity within the a-priori created network ( 5 rois) and some behavioral tests. I selected one -sample t-test statistical model, and entered my design matrix as follows:

1 23
1 43
1 25
1 34
1 23
1 56
 

and so on...


So my correlations with performance scores of 3 different tests were based on one-sample t-test, using 5000 permutations and setting the significant p-value at 0.05 (FDR method). I found some significant results involving all the 5 nodes of the networks for all the tests, but, surprisingly, the t value was the same for each edge across the three tests used. 

My answer is...did something not work? it seems unlikely that the t-scores are exactly the same...
