[Eeglablist] High variability in single trial ERSP result after each ICA run

[sara.kamali at uam.es]

Hi all,

I am using a public dataset to study the ERSP for different  
frequencies at single trials. I have noticed that when I run the ICA  
for the same subject, several times, every time I get a considerably  
different result when I look at the ERSP at the single trials!
The amplitude of each frequency curve varies highly for the same trial  
and the same subject!
Does this mean the results are not reliable and I should use another dataset?

Thank you in advance for sharing your opinion,
Sara
