Hi Tudor,

Seems to me that it could be just a display issue, as you didn't adjust the visualisation threshold (you have min = 2), whereas you run your Monte Carlo with a threshold of 0.05 (i.e. 1.3), and your cluster seem to be just in between.

Hope it helps,

Marie

It seems I'm getting the above problem only when lGI is the DV, and whether or not there is a group factor among the categorical predictors. I do have, however, lGI analyses where the significant cluster shows up fine both on the template and in the terminal window.
