[Schoffelen, J.M. (Jan Mathijs)]

Hi Gina,

That’s what I was afraid of. By replacing the .pos and .dim you made the data structure inconsistent. The number of source positions should be kept constant, i.e. you need to use a ‘template grid’ that is defined at the same approximate spatial resolution as your individual grids. The reason for this is that the numeric data (e.g. in source.avg.pow) should have the same number of elements as the size(source.pos,1).

Best,
Jan-Mathijs
