Hi Marco

Your script looks ok.

Yep, that is a known problem (sorry about that). The function
prepare_design is not working properly. I suggest to make a design
matrix in cfg.design by hand (similar to, but not completely the same
as in SPM). It is not difficult, and it will also make you more clear
how it works. Please have a look at

or if that URL does not work, then search the fieldtrip discussion
list archive for the string "cfg.design".

best regards,
Robert

PS note that you can also use timelockstatistics on the
'componentanalysis' part of the EEGLAB data, in that case you cannot
use channel clustering, but you still can use timepoint clustering
(so cfg.neighbours  should be []). You shoudl only do that if the ICA
components in the different EEG datasets are spatially the same (or
sufficiently similar, e.g. after clustering over subjects in the new
EEGLAB).
