[Eeglablist] Multiple .edf datasets to EEGLAB for analysis

[Makoto Miyakoshi]

Dear Mohith,

> My datasets are named as 304_sleep data.edf; 305_sleep data.edf...

But in your code, you are generating 'subj1.edf' 'subj2.edf'...

See this Wiki page, particularly this part:

cd('/data/project/example')
rawDataFiles = dir('*.bdf');
for subjID = 1:length(rawData)
    loadName = rawDataFiles(subjID).name;
    dataName = loadName(1:end-4);

    % Step2: Import data.
    EEG = pop_biosig(loadName);
    EEG.setname = dataName;
