[FieldTrip] strange time frequency results after converting data with eeglab2fieldtrip

[Marcus Heldmann]

I preprocessed my data (6 channels, 1Kz, minimum 97 trial/condition) with eeglab. Since I’d like to perform the time frequency analysis with field trip, I converted the data to field trip using the eegalb2fieldtrip function. However,  after the conversion I’ve got very strange results, meaning that for most of the frequencies I get zeros or NaNs. I am wondering, if I have to change something in the file structure. Does anybody has an idea what’s wrong?

Thanx for any help or hints, Marcus
