Hello,
I am working on EEG analysis. I have managed to get raw data by using Matlab but now I don't know how to preprocess it or filter the data. Can anyone please provide me with a Matlab code?
Your help would really be appreciated.
I have attached the raw figure that I have got.
The code you would use really depends on the conditions under which your data was recorded, what the paradigm used was, and what question are you intending on answering.
My suggestion would be to look at Matlab toolbox EEGLAB (https://sccn.ucsd.edu/eeglab/index.php ) from Arnaud Delorme and Scott Makeig (and many others). It's very well documented and has a great mailing list for more complex queries.
As Ty already wrote it is impossible to give you any advice without knowing what type of analysis you are planning to perfrom. Maybe you provide us with some examples what exactly you are interested in (e.g. event related potentials, coherence or power analysis etc.).
Another alternative to EEG lab is fieldtrip.
I can usually recommend to carefully think about all the filters you will use. There are different filter types such as FIR filters, IIR filters (Butterworth, Chebyshev, inverse Chebyshev and Elliptic). Also, you can use Matlab toolbox EEGLAB for EEG signal processing.
