Hi everyone, I have saved my EEG data as a .csv file. The structure of the file can be seen in the Image, so I basically have a problem with the information within the columns. Is it correct if I extract the column with the time values and the columns with the data of the EEG channels and leave the column with the epochs? And I had problems with importing the .csv file in EEGLAB, so I saved the .csv file as a .mat file as you can see in the code below. I would really appreciate your help.

EEG = readtable('motor-imagery-1-[2023.11.23-15.14.58].csv');
EEG_nurKanaele = EEG(:,[1, 3:10]); % here the column with the time values and the columns with the EEG channels are extracted
EEG_matrix = table2array(EEG_nurKanaele); % Convert the table into a matrix 
save('EEGDaten.mat', 'EEG_matrix'); % Save the matrix as a .mat file
