[Eeglablist] Changing group/condition after precomputation

[Makoto Miyakoshi]

Dear Chantelle,

> Makoto (or anyone else) do you have any suggestions on how to speed up
the rate of precomputing ERSPs?

I sometimes create multiple STUDYs with split subjects but with the same
design. You can use the precomputed measure later as long as the same
subjects and design are used.
