[Eeglablist] out of memory

Dear Mr Martin,

Why don't you try to increase the virtual memory to several GBytes from your
hard disk?

You can do that from Control Panel->System->Advanced->Performance(Settings
button)->Advanced->Virtual Memory(change button)

I have tried it and it worked for much larger data and workspace .. Note
that you have to restart the computer for changes to take effect.

You may also need to clear large variables from the workspace once you don't
need them again, by using:
clear var_name

Hope this helps
