Then compute/view plots of the differences between these two conditions.
Note there are also mutliple plugins (e.g. LIMO EEG) and an upcoming STUDY
update that may be useful.

Alternatively, you should be able to subtract one set of data from the
and then feed the differenced data to the eeglab function of your choice.
