[Eeglablist] Reading .mat file to EEGLAB

[Poikonen Hanna]

Hi all,

I have a simple question I didn't find the correct EEGLAB command for.

I’m trying to read in EEG data to EEGLAB (v2019.1 in MATLAB version R2019b) which is saved as .mat file. Previously, I’ve used successfully the command pop_biosig to read in .bdf files with a older version of the EEGLAB but it seems not to work with .mat files (below you can see the error message). Which command shall I use? I need to read the EEG data from the .mat files into EEGLAB to be able to re-reference, bandpass filter to later form .set and .study files.


Best regards,

For the .mat file, I get the following error message:

Command:
EEG = pop_biosig([ctrlpth condi '_Control' num2str(subj) '_WholeStimulusData.mat'], ...
    'channels', [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16], ...
    'ref', [1 2 3 4 5 6 7 8 9 10 11 12]);
