I am working on the cluster correction of an interaction image and found different results using easythresh and GUI. If I corrected the image at 3.1 0.01 in the GUI, there is nothing significant. However, if I correct the same zfstat image using easythresh at 3.1 0.01, I got two significant clusters. Is there an explaination for why this happened? Is the easythresh version valid?

Thanks,

Wen
