I went through all of the steps to run context dependent correlation analysis on one subject. I realize that a group analysis would be preferable but I am looking at pilot data with one subject to get an idea of how this analysis works. Everything appears to have run correctly. I created a dataset that contains all of the correlations between the seed region (Left Insula) and the rest of the epi data. When I look at the correlation map in the AFNI GUI it shows that many regions have a positive relationship (correlation) with the seed region (L Insula). And there are a few regions with an inverse relationship.
Here are my questions:
Is there a way to use the data that I have to get one "r" value for each of the regions that are correlated with the seed region? As the data stands now, I have a different "r" value for each voxel that I click on.
How do I set the threshold that I want? I have been sliding the bar that changes the p value but when I move it to a level that makes sense with the correlation map it is set to values like p = .00000002. Could this possibly be a real p value for the correlations that I am seeing?
Any help would be greatly appreciated!
Thanks!
