[Eeglablist] Making bipolar eye-channels

[Britta Hahn]

Hi all,
I am sorry to bug you with this really basic question, but I just cannot find the command that will allow me to make bipolar eye-channels. I have the left and right HEOG channels, and all I want to do is subtract one from the other, and put those data into a new channel. 
Thanks so much for any help you can offer!
Britta
