Hi everybody,<br>
<br>
Is it possible to filter data prior to epoching? And more generally
is it possible to epoch data that has already been preprocessed?<br>
<br>
I have tried without success many variations of this:<br>
<br>
1. Preprocessing step on continuous data with filtering.<br>
<i>cfg=[];</i><i><br>
</i><i>cfg.dataset = 'raw_data.fif';</i><i><br>
</i><i>cfg.bpfilter = 'yes';</i><i><br>
</i><i>cfg.bpfreq = [a b];</i><i><br>
</i><i>data = ft_preprocessing(cfg);</i><br>
<br>
2. Define trial.<br>
<i>cfg =</i><i> ft_definetrial(cfg);</i><br>
<br>
3. Preprocessing step for epoching data on filtered data.<br>
<i>final_data = ft_preprocessing(cfg,data);</i><br>
<br>
<br>
Thank you for your help.<br>
