I have EEG data that comes in the form of a 3D numpy array (epoch * channel * timepoint). timepoint is a 256 element array containing each sampled timepoint (1s total, at 256Hz). epoch is an experimental trial.
I'm trying to import the numpy array into a form Python-MNE (http://martinos.org/mne/stable/mne-python.html) understands, but I'm having some trouble
First, I'm not sure if I should be importing this raw data as a RawArray or an EpochsArray. I tried the latter with this:
ch_names = list containing my 64 eeg channel names
allData = 3d numpy array as described above
info = mne.create_info(ch_names, 256, ch_types='eeg')
event_id = 1
#I got this from a tutorial but really unsure what it does and I think this may be the problem
events = np.array([200, event_id]) #I got this from a tutorial but really unsure what it does and I think this may be the problem
raw = mne.EpochsArray(allData, info, events=events)
picks = mne.pick_types(info, meg=False, eeg=True, misc=False)
raw.plot(picks=picks, show=True, block=True)
When I run this I get an index error: "too many indices for array"
Ultimately I want to do some STFT and CSP analysis on the data, but right now I'm in need of some help with the initial restructuring and importing into MNE.
Whats the correct way to import this numpy data that would make it easiest to complete my intended analyses?
