How to get Alpha waves using NeuroSky and Matlab?

Hey Guys; I am using NeuroSky headset. I can get raw EEG data without problem. But when I want to get Alpha, Beta , Gamma,... waves using the below code, it returns "0" and never enters to "if" block!

            TG_DATA_ALPHA1 = 7;
            if(j == 5)
                if (calllib('Thinkgear','TG_GetValueStatus',connectionId1,TG_DATA_RAW) ~= 0)
                    data(i,j) = calllib('Thinkgear','TG_GetValue',connectionId1,TG_DATA_RAW);
                end
            end

So what is the problem? Why I can get the Raw EEG data but I can't get Alpha and other waves? I am using the code of this question : http://www.mathworks.com/matlabcentral/answers/69208-store-eeg-data-to-matrix-and-save-it-to-csv-file

Also I am using NeuroSky mobile Headset. Can you guide me what is wrong here? Thanks

Hello.

Have you been able to solve the issue? I am also facing the same problem. I would be thankful if you could tell me how you resolved this problem.

Thanks.

First, you need to record raw EEG with Neurosky. You may find how to record raw EEG in Neurosky documentation. After you should use Wavelet or Fourier Transform to extract frequency-bands(Alpha, Beta, Theta, ...). Take a look at the below link: https://www.researchgate.net/post/How_do_I_analyze_the_below_EEG_raw_data_and_extract_brain_frequency_bands_from_it

did you use the NeuroSky MindWave?? or the 2009 product that is called NeuroSky headset! if you used the first one can you please share the whole code that you used to read the Alpha waves!! it would be a great help! thanks in advance!!

Thank you for answering but this code is for reading meditation eSense from a "NeuroSky Mindave Mobile" and what I am looking for the code that reads this same but from a "NeuroSky Mindave"!

It appears to me that the code would work for Mindwave. It needs a COM port to communicate over, but it does not care whether the COM port is a Serial Over USB or is a Bluetooth port.
