Trouble selecting data #4
Description
I am attempting to replicate the analyses used in the paper. I have created a reproducible example below where 3 EEG files of 180 seconds are created. The data has 3 epochs of 60 seconds.
- Pre-oxy
- Surgery-S1
- PACU
I continue to get the following error
I have also attempted to run each epoch individually (so there are no events) and I get the same error.
Below is my code
required files (events and channels).zip
%% Create fake data and save it as a *.mat file
load('C:\Program Files\MATLAB\R2019b\toolbox\nnet\nndemos\private\eegdata.mat')
x = eegdata;
clear eegdata
data = [repmat(x,16,112)];
data = data(:, 1:45000);
EEGdir = 'C:\Users\Gertrude\Desktop\Microstates\raw\Merged\GitHub\';
% Create 3 identical copies which I will import into eeglab with event

save(strcat(EEGdir, 'S01.mat'), 'data');
save(strcat(EEGdir, 'S02.mat'), 'data')
