I am trying to process some MRCP Signals taken from this (BCI Competition IV-2b,motor imagery) and I want to import the signal from GDF file using Python as I know it can be done easily on MATLAB. Then , I would then like to apply STFT on the signal using this method based upon this description
Short time Fourier transform (STFT) was applied on the time series for each 2 s long trial. In case of 250 Hz signal, this is corresponding to 500 samples. STFT was performed with window size equal to 64 and time lapses equal to 14.
.Any help would be appreciated
