Thank you for your reply!
But i have a question about your answer.

1. The p-value of the data exported by conn in SPSS and p-value of t-test in conn is very different.
I can't understand why. Is the t-test method in conn different from the method in SPSS?

2. And the p-value at the top of the t-test(top line in the results table of the graph theory window)
Can uncorrected p-value and FDR p-value be equal?
When i choose uncorrected p-value, there is a significant roi but not FDR.
Both total p-values are the same.What is the difference between uncorrected p-value and FDR in t-test?

3. What are the means of 3 ways(one sided(positive), one sided(negative), two sided) in Network edges(adjacency matrix threshold)?
And what are the three methods(one-sided(positive), one-sided(negative), two sided)at the analysis threshold(p-value)?
What is the difference between the two?


Please answer my question.
Thanks as always.
Best regards.
