Hello,
C3 and C4 are identical to C1 and C2 and so can just be fully removed. The yellow box is used with FEAT to control if the contrast is included in the web report, and is not relevant for randomise.
Kind Regards
Matthew

However, when I get my results, there is a 'tfce_corrp' stats created, which confused me on the meaning of the yellow box next to the contrasts.
