Nietzsche discovered this because she is using a funky statfun that crashes with nans in the data (being defined on the outside voxels). As far as I remember, in the past ft_sourcestatistics pruned the 'dat'-matrix that went into ft_statistics_montecarlo to contain only the inside voxels. It could be that this feature has disappeared.

added test data and funky statfun to /home/common/matlab/fieldtrip/data/bug2898

I am running into it now as well. Will investigate and try to fix.

Update: I verified this quickly by hand, and this indeed the case. I suspect that this may have consequences for spatial clustering

I have provided a fix for this in a branch of my FT fork: bug2898
