Hey! 1) Difficult question. Power analyses are essentially working backwards from a traditional statistical test and getting to the minimum N. However with non-parametric tests (which at the statistical level...

Well, this current reply wasn't so quick... I sort of agree with your hesitation on previous studies... yet while I agree this problem is basically all of science; especially neuroscience...

Hi Corentin, I'll reply to both your mail and this message at once :) Regarding the balanced groups, there is no easy and quick way around this unfortunately, especially not...

Regarding your question on the p-value calculation: > Digging into the ept_TFCE & ept_TFCE_ANOVA functions, I couldn’t understand the rational behind the computation of p-values (see below): ``` edges =...

The data can be used directly if already loaded into the matlab workspace... ``` Results = ept_TFCE(... group_1_data, ... % subject by channel by frequency bin group_2_data, ... % also...

Good luck! I'm also working on a general linear model version so that you can include any number of factors and levels in your analysis, but the permutation strategies for...

The scripts treat the second dimension as time by default, and if you put in the sampling rate as your frequency bin size then it could have been translated directly...

A few further comments and suggestions... --- How are you calculating the frequency bins? If bin "12" is equal to 2.75Hz it sounds like you are using quite long time...

4 second windows actually seems fairly reasonable. This will give a frequency resolution of 0.25Hz, at the expense of some stationarity assumption in your signal. So I suppose I'm curious...

Sorry, I've been away a little while. That looks great! I hope it was also able to produce some meaningful results!
