[Eeglablist] Get statistical parameters of power spectrum analysis

I'd like to receive exact numeric p-values as well as the other statistic parameters of the power spectrum analysis, for every single electrode or at least for the electrodes with significant difference (p=.05). I just know how to plot the power spectra of different variable comparisons with the option of certain p-values or "exact".
I've read the attached topic 'Get the p-value', but with the mentioned solution I don't get exact numeric p-values and the statistic test corresponding parameters of each electrode using power spectrum plots (alpha-frequency, beta etc.).
Can anyone give me advice?
Thanks in advance!

[Eeglablist] Get the p-value <https://sccn.ucsd.edu/pipermail/eeglablist/2016/011065.html>
Dear Edward and Andria,
I got two pieces of advice for you.
To obtain exact p-values for the significance-masked spectra,
1. The simplest way to do it is to select "exact" or empty in the p-value
2. That should be done from the command window. The easy way should we
something like this (ie. for channel AF4):
[STUDY, specdata, allfreqs, pgroup, pcond, pinter] =
Looks like the solution 2 is the right way to do it with coding.
