Hi !

I am trying to use the "plot effects" button in the ROI-to-ROI second-level results (CONN20.b, Matlab 2019b, Ubuntu 18.04.6 LTS). The button works ok in the ROI-to-voxel second-level results, however in the ROI-to-ROI second-level results a error message is shown in the command line and the menu "Loading data. Please wait..." keeps being displayed but nothing else happens.
Example of second-level results that I would like to use the "plot effects" button and the error message below is shown. I tried other contrasts and the same error is shown.

Thank you for your attention.
