[Eeglablist] Data change when updating eeglab from version 10 to 12

[Makoto Miyakoshi]

Dear Nicolas and Arno,

> some of these data, the stats are changing, whatever stats option i used
(parametric, permutations, with or without holms correction and bonferoni
correction).

Permutation results may change because this approach is based on random
permutation. However parametric test result should not. Could you check it
again?

> ERP's topographic map's ( the significant channels are not the same each
time i replot).

Significant channels? You mean you are running STUDY analysis using
channels? If that's the case I'm not experienced with it.

However, changing topographic maps is familiar with me. However, I want to
know exactly what you are doing (using ICs or channels)
