GUI LSL stream question on FFT Transform

When we use LSL pipe of the GUI it gives 25(approximate) readings(frames) per second. cyton got only 250 total data points per second. How you manage to maintain that rate. How many data points use for each FFT transformation.?

Another, probably better option, is to use the Brainflow library,

I used LSL data pipe for acquire the data. Even I on the filter on LSL settings the data that recorded are not filtered. The time series data that is shown by the GUI is not similar to the data I got using LSL pipe. When I plot those data it is like a periodic sinusoidal wave. I applied all filters in GUI properly and the time series shown by the GUI is much better. impedance also below 20K. but the data got by lsl pipe is not a filterd one.
Suggest you try Brainflow, it is highly supported and any questions you ask on the Brainflow Slack are usually answered the same day.
