Enquiry Regarding data processing of OpenBCI_GUI

in OpenBCI_GUI
I am using the Cyton for my Final Year Project regarding the EEG signal during driving emergency. As I need to compare the data of EEG and another set of data from the driving simulator, I need to find out the EEG Time series plot, FFT Plot and Band Power at specific time period. Therefore, I would like to ask is there any other method other than importing the data into EEGLAB that I can analysis the EEG data at a precise time frame. Thank you very much.

    Hi Hei,

    Is your application a REAL TIME / feedback situation? Where the driver in a simulator is monitored in realtime and the EEG shows his response during a simulated emergency? Then if certain EEG metrics are reached, the driver is alerted?

    Or does your analysis happen offline after the simulated driving session?

    In the case of the realtime, you can process the live Cyton data stream using a number of different libraries, depending on your language preference (such as Python, C, etc.) Each of these languages then also has available a DSP Digital Signal Processing library, where you can take the live data stream and compute FFTs, band powers, and such. There is also a version of EEGLAB that runs in realtime, called BCILAB.

    If you are only processing data offline, then you could use any language DSP that can parse CSV data from the OpenBCI_GUI.

    Regards,

    William

    Dear William,

    Thank you very much for the reply. I am looking for an offline analysis as I have to compare the EEG data with the data in the driving simulator after the driving lesson. Is there any 3rd party software you recommend for offline analysis? I have tried EEGLAB but I find it hard to use matlab and to import the data to EEGLAB from the raw file taken from OpenBCI. Thank you very much.

    Best Regards,

    MNE is based on Python


    But you can also just use Python with any of the DSP packages available,
