[FieldTrip] RE : Best way of saving data in format that fieldtrip will understand

[VERSINI JEAN-BAPTISTE p1207642]

Hello,

data.trial is a <1 x NTrial cell> and each cell in it is a <NChan x NSample double>
data.time is a <1 x NTrial cell> and each cell in it is a <1 x NSample double>, e.g. [0 0.2 0.4 0.6 0.8 1] for one second trial sampled at 5Hz.

Hi,

I think I managed out doing this but there are some points I like to discuss.

My EEG stream is made of 14 channels. Sampling rate is 128.
I don't have separate trials but a single continuous recording. So if
I understand correctly I have to create the data structure like this:

data.fsample = 128
data.labels = cell array of channel labels
data.trial = {[14xNsamples]} (Single element cell array containing the
whole EEG data)
data.sampleinfo = [1 Nsamples]
data.time = {linspace(0, Nsamples/fsample, Nsamples)} ??

What should the data.time be? Is it the whole recording duration
divided by Nsamples?

Thanks.
