[FieldTrip] Difference wave calculation

Hi Fieldtrip list,

I'm quite new to using Fieldtrip for analysis and can't find any information on how to create difference waves, for example to examine MMN activity. Currently I've just been making a new structure and adding items from the ft_timelockedanalysis function, subtracting the standard from the deviant for the .avg and .var fields while keeping the rest intact. 

Are there any tutorials available that can show me the recommended way to go about this? Alternatively, can anyone working with difference waves give an example of how they calculate them?
