[FieldTrip] ft_sourceinterpolate with stats data

Hi Andreas,

all the chiefs are on vacation right now, and I do not know if it should 
work or why it does not. Therefore, I created a bug on bugzilla:
http://bugzilla.fcdonders.nl/show_bug.cgi?id=2218
You can also sign up there and add yourself to the CC list to stay 
informed about the progress on this. In the meanwhile I would suggest to 
do as Haiteng proposed, as this is the only way to go right now.

Thanks for reporting :)
Best,
Jörn
