Minimum T-values in ROI-to-ROI
Dear CONN experts,

I am exporting the results of positive and negative T-tests from the ROI-to-ROI results explorer, involving multiple ROIs, in order to plot connectivity matrices with T-values in MATLAB. I use "export mask" and save as a .mat.

I have two questions regarding this function:


1. In order to threshold the colorbar correctly and report the results accurately, it would be useful to know the minimum T-value when I threshold at, for example, analysis-level p<0.05 FDR.
I have not been able to find the precise T-thresholds in the CONN ROI-to-ROI results.
Is this possible?

2. Preferably, I would export the results of a two-tailed test. However, the matrix R that is exported only contains absolute values.
Is it possible to export the matrix and keep the negative connectivity values?


Best wishes,
Andreas
