Hi Joao,
Yes there is a eye movement correction procedure algorithm that has been
translated into matlab by Bill Gehring. Please email me or him if you want
a version. Thanks,

> Dear EEGLAB list,

> I'm trying to extract independent components for my ERP single trial

> base line of the trials is removed by using a pre-trial of 300 ms.
> Non-trials are cut out before the pre-trial. All trials, i.e. non-trials

> function.

> As you can see many components are localized around one electrode
> (3,4,5,6,8,9,10,11,12, ...). Almost all of my subjects have these focused
> components. Is this normal or do I have a error in my setup? Any help is
> greatly appreciated.
