How to create electrode position and electrode position File in eeglab

This article mainly introduces how to create electrode position and electrode location file in eeglab, which is very detailed and has certain reference value. Friends who are interested must read it!

Make the electrode position by yourself

Step 1: run the matlab program and create a file

Clear, close all;clc; chanloc=pop_chanedit (''); [fileName filePath] = uiputfile ('* .mat'); save ([filePath fileName], 'chanloc')

When running, the following dialog box pops up, and click Cancel:

After clicking Cancel, the following dialog box pops up:

Step 2: start creating the electrode, now create the second electrode:
