[FieldTrip] Error using fixdimord ("chan_freq_unknown") when I attempt to plot stat

[Bianca Trovò]

Hi, Eelke,

Thanks for your answer: apparently the problem arose from the fact that I
was feeding the cluster based permutation test with regression values for
which I had to create a 'fake' ft structure. In order to do that replaced
the powerspectrum variable of a TFR output with the R values, but there was
a mismatch between the time dimensions of the two. Therefore, the *stat*
had the 'time' field with a different dimension from the 'powerspectrum'
field and this created the unexpected dimord "chan_freq_unknown" problem.

Cheers,
Bianca
