[FieldTrip] ft_sourceplot stubbornly projects rays beyond the head

[Tzvetan Popov]

Hi,
How about you remove the second input argument to ft_sourceplot? Leave only sourceint.

I'm pretty sure that the sources are properly estimated, with MRI, sourcemodel, headmodel and sensors aligned. They can be correctly visualized using ft_plotmesh function; moreover they nicely match with source estimation preformed in other software package. However all our attempts to visualize them onto brain anatomy failed.
