[FieldTrip] Cfg.latency in ft_sourceplot not working?

[Stephen Whitmarsh]

Dear Emilie,

Given a high a priori probability that the plotting function is okay, I
would first check whether the data (sourceIntpl_Victim.pow?) is as
expected, e.g. by checking if the dimensions are as expected, and plotting
a single voxel over time using just MATLAB's plot function, or just looking
at the numbers and checking if they change over time.

Cheers,
Stephen
