Hi everybody,

I am trying to configure the CursorTask application and I would like that the features (power spectrum) to control the BCI are computed every 20 ms using the past 500ms of data. I think "using the past 500ms of data" is controlled by the "WindowLength" parameter. However, I did not find the parameter to fix that the features are computed every 20ms.
Is it the "EvaluationsPerBin" parameter?

Thank you for your help,

Fanny

Fanny,

the WindowLength parameter [1] controls the duration of data that is used for each spectral estimate. The SamplingRate/SampleBlockSize controls the number of spectral estimates per second.
