Dear Baris,

You can set the default lowest frequency to be lower (3 Hz for  
The default lowest frequency is calculated based on your epoch length  
and in some case, the default is too high.
I suggest using frequency limits defined manually "'freqs', [3 50]" in  
the ERSP/ITC parameter edit box.

Hope this helps,
