DPABI Correlation-analysis and FDR

Submitted by evast001 on

Hello

I am using DPABI to correlate resting state connectivity of a seed region and various behavioral measures. I've entered my zFCmaps in "group images" and added a text file of the behavioral data in "correlation seed series". When I use the resulting R-file as overlay in DPABI viewer, I see the areas of the brain where my seed region and behavioral data correlate, correct? I also used FDR and set the q value to 0.001 but still had a lot of brain areas showing connectivity. I ended up setting it to 0.00001 to get easier overview of the specific regions I'm interested in. Does it make sense to have the q-value as 0.00001 or is this wrong?

Thanks in advance!

Hi,

where my seed region and behavioral data correlate: it's possible.

FDR 0.00001: it's unusual. How many subjects do you have? You can try GRF correction to see how the pattern is.

Best,
