I have a question related to Monte Carlo tests of multiple comparisons. When I conduct some of my analyses, there is no difference between before and after Monte Carlo (i.e. same size and coloured regions appear on the inflated brain after I click on the analysis in the Description box), whereas for other analyses I get large matt coloured clusters with significance values stated for those clusters in the terminal. Also, I have completed one analysis whereby the before and after Monte Carlo coloured clusters are the same but only one of the clusters is stated as significant in the terminal.

Does anyone know whether the clusters that appear after Monte Carlo simulation, but are not stated as clusters in the terminal, are significant?
