[Eeglablist] problems with the statistics module in EEGlab

[Bruce Bolster]

Hello:

I am trying to perform parametric analysis on resting state EEG data.  The toolboxes work to generate individual and averaged plots, for both spectral power and scalp topography, for individual frequency bins including theta, alpha  beta and gamma, defined within my study as 2-7 Hz, 8-12 Hz, 13-30 Hz and 30 - 55 Hz (considering only frequencies below 60 Hz to avoid 60 hz artifact).

Using a properly constructed "study"  I am trying to do a simple pairwise contrast between the eyes-open and eyes-closed condition across the various spectral domains, for particular electrodes as regions-of-interest.  Using the tools available in the "study" GUI, the averaged spectral figures and the topographic plots show the expected differences in the alpha spectrum, as a reality check.  If I drill into a particular electrode as an ROI, the plotting program will generate spectral power  plots for both individual participants as light blue lines, and the averaged power as a black line.  However the statistics function appears to be dysfunctional, and will not plot any values into the output graph.  This seems to be a program issue - has anyone got a solution?

thanks
