[Mne_analysis] splitting fif files

[Alexandre Gramfort]

Hi,

if you're willing to give it a try you could easily split your raw fif
file in python.

>From a Linux machine at MGH do in a terminal:

setenv PATH /usr/pubsw/packages/python/epd/bin:${PATH}

then the following python script should help you do what you want:

-------- beginning of script

from mne import fiff
from mne.datasets import sample
data_path = sample.data_path('.')

fname = data_path + '/MEG/sample/sample_audvis_raw.fif'

raw = fiff.Raw(fname)

# save the first 150s of MEG data in FIF file
raw.save('sample_audvis_meg_raw_part1.fif', tmin=0, tmax=150)
# save the rest in a second FIF file
raw.save('sample_audvis_meg_raw_part2.fif', tmin=150)

--- end of script

if you're lost I can help you tomorrow.

you can get more info at  https://martinos.org/mne/mne-python.html
(visible internally only for now)
and if you feel like it the code is public at
