[FieldTrip] colored or grey output from ft_singleplotTFR 'mask'

[NIEUWLAND Mante]

Dear Fieldtrip users,

With the same singleplotTFR script (see below), which masks the differenceplot of two conditions using the statistical result, I seem to get the expected color output in one dataset (1c1d.pdf) but unexpectedly grey output in another dataset (3c3d.pdf) *irrespective of how I set the z-lim*. I've also tried changing. Does anyone have an idea how this can happen?

Cheers,

Mante
