[Eeglablist] Numerical Values

[Arnaud Delorme]

Dear Carlo,

after plotting the spectrum, use "eegh" look at the history. Then add additional output to the std_specplot function (the example is with channel Fpz below).

[ STUDY specdata specfreqs] = std_specplot(STUDY, ALLEEG, 'channels', { 'Fpz' });

You may then export the numerical data in specdata into your prefered software. For instance, to export the data for the first condition, type

specdata1 = specdata{1};
save -ascii specdata1.txt specdata1;

Best,

Arno

I would now like to get the numerical values in the frequency range of interest (8-13 Hz) for each condition, for each subject, in order to be able to compute ERD/ERS values for each of the two experimental conditions using Pfurtscheller's method. How can I obtain such numerical values with EEGLAB (or MATLAB)?
