BCI BAsics

[Sri_usw]

Hello,
I am sri. I just started to work with BCI2000. I used Signal Generator ,FFT Signal Processing and Dummy Application. I have set the sine frequency as 100Hz in Signal Generator(source module) and only 4 channels in transmitted channel list. When I run the application, its running fine but when I applied the low pass filter of 30Hz still I am able to see 100Hz frequency in the frequency domain. can you please clarify me why its happening?

ii)I have and emotiv research sdk headset . I have acquired a motor imagery dataset and would like to observe the frequencies (analyse) in certain channels. Since its an offline analysis, do I need to use offline analysis module of BCI2000 which is analyzing the signal in matlab. or is it possible to analyse in BCI2000 without using source module.

Regards,
Sri.

Sri,

You asked several questions all over the message board. You e-mailed the mailing list. You even messaged me directly. The questions are not consistent. I cannot answer everything.

Please start by following the mu rhythm tutorial. Then try to post here and limit your posts to one line of questioning.
