Dear Stephen Whitmarsh,<br>
<br>
Thank you for your kind and rapid response.<br>
<br>
I tried to run your advice, however the problem remains the same. :(<br>
<br>
May there any other possible solutions?<br>
<br>
Thank you.<br>

Sorry, I just saw your other question.<br>
<br>
I am a beginner, so I don't know what to expect in terms of values of<br>
sample & ndatsample relating to your question. This is the struct of the<br>
data:<br>
<br>
temp =<br>
<br>
struct with fields:<br>
<br>
hdr: [1×1 struct]<br>
label: {306×1 cell}<br>
trial: {[306×227572 double]}<br>
time: {[1×227572 double]}<br>
fsample: 2000<br>
grad: [1×1 struct]<br>
cfg: []<br>
<br>
Thank you again.<br>
<br>
Best regards,<br>
<br>

Hi Yanki,<br>
<br>
It seems your datastructure is a single trial of 227572 samples @ 2000Hz =<br>
113s, i.e. about 2 minutes.<br>
Whatever is causing the issue, I am not sure that is what you want to<br>
calculate a 2 second TFR on, right?<br>
<br>
You should probably first segment your data into trials. Perhaps start with<br>
the event-related tutorials on the fieldtrip wiki and adapt it to your data?<br>
<br>
Best wishes,<br>
Stephen<br>
<br>
<br>

<br>
I would like to analyse Emotiv Epoc+ EEG data using Fieldtrip.<br>
The protocol is a simple resting state (3 min of eyes open and 3 min eyes<br>
closed).<br>
Can I have information on the pipeline necessary to analyse this data?<br>
Thanks<br>
