[FieldTrip] Cfg.latency in ft_sourceplot not working?

[Britta Westner]

Dear Emilie,

note that you are plotting power. This is computed during ft_sourceanalysis
based on your covariance matrix, so it represents the latencies you
computed your covariance matrix on. The time axis in your source is
referring to the field ".mom", which contains time series. Changing the
latency has no effect on plotting the power, it has no time axis anymore.

Hope this helps,
Britta
