[Eeglablist] Eeglab in Octave

Dear Nathan,

thank you for your answer. This was the feeling I had about Octave too. 
Since most EEGLAB functions are about delivering graphical outputs, it 
seems relatively unrealistic that we will port them to Octave anytime 
soon. Also, with a limited amount of human resource, we have other more 
urgent things to implement (component clustering etc...). If someone 
wants to adapt a specific signal processing function to Octave, they 
should ask us first for the latest version of the function (which is not 
necessarily the version distributed on the internet) or we might not be 
able to take their contribution into account.

Best,

Arno
