[Mne_analysis] Read head position from .fif file

[Benoît MARTIN]

Dear all,

I am actually trying to read the head position from my .fif file,
but I get this error: "Could not convert string to float"

here is my line of code:


raw_fname = data_path + 'raw/cb140229_mag_run1.fif'
# Read head position
head_pos = mne.chpi.read_head_pos(raw_fname)      [error is at that point]
raw_sss = maxwell_filter(raw, calibration=cal_fname,  cross_talk =
ctc_fname, head_pos=None)


I am wondering what I am doing wrong, or if I can read head position from
the .fif file.
Any help is welcome,

Best,
Benoît MARTIN
