[Eeglablist] .set format python

[Bruzadin Nunes, Ugo]

Dear Rita,

Here's a piece of code I have from a while ago. I'm not an expert in python, but the mne function  "raw = mne.io.read_epochs_eeglab(filename)" reads .set and .fdt, if I'm not wrong. I hope the code still works. Once you have the .fdt/.set in .fif you can use it in mne library. I clearly import too many libraries here (the code was much longer), but hopefully you can get to the gist.

-------
import os
import mne
import os.path as op
import numpy as np
from time import time
from mne import io, Epochs
from matplotlib import pyplot as plt
from mne.preprocessing import ICA
from mayavi import mlab
from mne.minimum_norm import (make_inverse_operator, apply_inverse,
                              write_inverse_operator)

path = 'c:\\UGO\\MNE\\sLORETA_project\\'

folders = []
files = []
filenames = []
setfiles = []
fdtfiles = []
eventfiles = []
headmodels = []
participants = []

#get files in the folder
# r=root, d=directories, f = files
for r, d, f, in os.walk(path):
    for folder in d:
        folders.append(os.path.join(r, folder)) # adds folders to array folders
    for file in f:
        files.append(os.path.join(r, file)) # adds filespaths to array files
        if not '.' in file:
            filenames.append(os.path.basename(file)) # adds all filenames without extension (raw)
            if file[0:4] not in participants:
                participants.append(os.path.basename(file[0:4])) # if participants was already added, it is not added again
        if not 'old' in file:
            if '.evt' in file:
                eventfiles.append(os.path.join(r, file)) # adds the events to array events
            if '.sfp' in file:
                headmodels.append(os.path.join(r, file))
            if '.set' in file:
                setfiles.append(os.path.join(r, file))
            if '.fdt' in file:
                fdtfiles.append(os.path.join(r, file))

for i in setfiles:
    fname = i
    raw = mne.io.read_epochs_eeglab(fname)
    raw.save(fname + '-epo.fif')

Dear Rita,

See also this page about reading Matlab files in Python

https://sccn.ucsd.edu/wiki/EEGLAB_and_python

Note that as of this day, the combined EEG and MEG community primarily uses Matlab (totaling 90% of citations).

Best wishes,

Arno
