1st level analysis 一阶分析
一阶分析至少需要两种文件 (categorical variable 和 continuous variables) 的其中一种。
LIMO EEG expect (at least for now) that your have your conditions coded separately for each trial - this should be a single vector with all your conditions (basically you can export this from your EEG structure). A continuous might some measures from your stimuli, the response (like coding incorrect responses to remove some variance), or RTs.
Your categorical variable is basically your condition code for each epoch. I assume you have an epoched dataset? If so, for each file you need to generate a list with an integer per row corresponding to the order of trials in your epoched file. The continuous variable would be the same but it would not bin your data into condition. So for example it would be the degree of brightness for each picture (hence, continuous).
As Bastien point out, any integer works – also if there are some conditions you want to remove you could just put a NaN. Files can be .mat or .txt

其中，categorical variable 可以由
2nd level analysis 二阶分析
创建 expected channels 和 neighbouring channels
channeighbstructmat = limo_expected_chanlocs(data_set_name, path, neighbour_distance);
[neighbours, channeighbstructmat] = limo_get_channeighbstructmat(EEG, neighbdist);
