Errors with training CSP filter in Openvibe example scenarios.

Post by reconnel »

We are trying to run the CSP motor imagery example scenario that comes with OpenVibe. When running the CSP filter trainer scenario we get the following errors:

[ WARNING ] Box <CSP Spatial Filter Trainer> sends inconsistent chunk dates on output [0] (current chunk dates are [1258224091136,1258291200000] whereas previous chunk dates were [0,0])
[ WARNING ] 'Stimulations' streams should have continuously dated chunks
[ WARNING ] Please report to box author and attach your scenario
[ WARNING ] <Player::can not reach realtime> 3 second(s) late...

Does anyone know what these errors mean and how to solve them?

Hi
It's not an error, just warning. Chunk dates is a common warning without incidence. For the reach realtime it's just during train he have a lag.
