Dear Gemma,
have a look at the 'contrast' structure available in the workspace after
a plot, in particular contrast.y.
Best regards,
Guillaume.

It seems logical that each participant must contribute a value to this plotted number, only I don't know where to extract the individual's contributing data. I can of course, see the final plotted values by looking in the variable 'betas', however, this doesn't give each participants' data. I'd like to see what drives the interaction at this spatio-temporal location by running statistical tests on the data I'd like to extract; any help gratefuly received.
