External Email - Use Caution
Dear all,
I am using MNE for EEG analysis on my MacBook Pro on both mac OS and Windows (double boot).
Today, I could not apply projectors on Windows but I could on mac OS. The error raised on Windows is:
C:\Program Files\Python\Python38\lib\site-packages\mne\io\proj.py:641: RuntimeWarning: invalid value encountered in greater
nproj = np.sum((S / S[0]) > 1e-2)
The error was raised when doing:
raw = mne.io.read_raw_fif(fname, preload=True)
raw.set_eeg_reference(ref_channels='average', projection=True) # CAR
eog_projs, _ = mne.preprocessing.compute_proj_eog(raw, n_grad=0, n_mag=0, n_eeg=1, reject=None,
no_proj=True, n_jobs=1)
raw.add_proj(eog_projs)
raw.plot(scalings=DEFAULT_SCALINGS)
Note that using only one of the 2 projectors raises the same error; and using raw.apply_proj() does it as well.
Same file with same script on mac OS is working fine. Any idea for a solution?
Have a nice day,
Mathieu Scheltienne
