[Eeglablist] Announcing GEDAI: A new EEGLAB Plugin for unsupervised artifact correction

[George Papaioannou]

Dear colleagues

I downloaded the GEDAI pugin, following all instructions on how to run it.
When I run it I get the following error: Error: File: GEDAI.m Line: 95
Column: 1
This statement is not inside any function.
 (It follows the END that terminates the definition of the function
"GEDAI".)

Could you please fix the problem in the script of the function ?

Best regards

Dr G. Papaioannou, PhD
