[Eeglablist] examples of how to get numerical data out of ERSP and specturm?

[Andrew Hill]

Hi Arno, and list.

I'm still chasing the elusive extraction of numerical ERSP data.  

I'm able to get the times and frequencies out per the example below, but my "erspdata" is a 3 * 4 array of [4-D Double] structures, e.g. session * group.  Is there a straightforward way to export a summary of these to facilitate import into Excel, SPSS, etc?  

I've been spoiled by how much I can do with EEGLab without stellar matlab skills; any advice here is welcome :)

Best,
andrew
