[Eeglablist] STUDY Spectral Plots & Statistics

I have a couple of questions regarding interpretation of the statistical output from STUDY channel spectrum measures.  I want to compare the change in spectral power across 4 conditions for a single group of subjects.  From STUDY plot channel measures menu, I select ALL channels, plot topography at a specific frequency (e.g., 12 Hz), and get one plot for each condition and one p-value plot.  What does the p-value plot represent...the significant change across ALL 4 conditions?  Also, is there an easy way to export the statistical results so I have the actual p-values across channels?  I'm sure these questions have been addressed in previous postings, but I couldn't locate the answers  in recent threads.

Thanks!
