Hi Brian,

Is the neural activity computed in your data? Please check whether
you have besides the field source.avg.pow also the field
source.avg.nai. Computing the neural activity index requires
cfg.projectnoise=yes in sourceanalysis, and furthermore requires that
you call sourcedescriptives after sourceanalysis. I suggest that you
use the new sourceplot function instead of the old sliceinterp function.

best regards,
