[Eeglablist] question about ITC/ERSP

Dear all,

I meet one question when I run the "study"- "pre-computer channel measures"
to calculate the ITC and ERSP. The epoch is 1100ms, including 200ms
pre-stimulus baseline.
My parameters for ITC and ERSP is following:

" 'cycles', [1 0.5], 'baseline', [-200 0], 'freqs', [3 4 5 6 7 8 9 10 11 12
13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37
38 39 40 41 42 43 44 45], 'alpha', 0.05".

I test it, it works. But when I run it, I got one information:
"Finding closest points for time variableTime values for time/freq
decomposition is not perfectly uniformly distributed."

I am not sure what it means. Are the parameters ok? or There are something
wrong?

Thank you very much!!

Best,
Pengmin
