I don’t know how to plot the results of my group analysis. Of the brain graph measures of a connectivity study. I do click right and try to plot but nothing appears. I don’t know if this is related to my connectivity matrix having 84×84 dimensions and the atlas 148 ROIs.
As you already mentioned, you should have the same number of ROIS in the atlas and in your matrix. In this case, you should only keep the rows of the 84 regions used for the analysis in the atlas file.
