I tried to run this 3 lines of Code:

import mne

myfile = 'test_raw.fif'
raw = mne.io.read_raw_fif(myfile)

It should load a .fif-File Its the example from http://martinos.org/mne/stable/index.html

When I try it with their sample-Data it works! When I run it with my own recordet Data I get this Errorstack:

I downloadet "brainstorm" wich can illustrate .fif-Files. The Sampledate from MNE can be displayed. If I try mine, they wont.

  • Can you try the following?: `mne.io.read_raw_fif(myfile, allow_maxshield=True)` – armatita Feb 21 '17 at 12:41
  • Tried this also ... Does not work :/ – Flx Glandorf Feb 21 '17 at 12:42

    Is this a binary file? Do you have an alternative software or library to check if it loads? That is to say: are you sure your file is correct? (Disclaimer: I'm not in the field so I don't really know what kind o standard do `fif`files follow). – armatita Feb 21 '17 at 12:46
  • As i said, if I load the Samplefiles with "brainstorm" they work and I get them displayed. If I try to open my files with this programm, I get an error. – Flx Glandorf Feb 21 '17 at 13:27

  • Than perhaps its either a library bug, or an incompatibility in the file standard (different versions of `fif`). But I'm just guessing. My suggestion is that you contact the MNE developer(s) directly (even if you are waiting for an answer here in SO). Sorry I couldn't be of more help. Best of luck. – armatita Feb 21 '17 at 13:43
  • That was my guess too! Thank you so far! – Flx Glandorf Feb 21 '17 at 13:48
