[Mne_analysis] forward solution of data with bad channels

[Maximilien Chaumon]

Dear all,

I'm trying to compute a forward solution with data that has bad channels.

raw = mne.io.read_raw_fif(raw_fname)

# raw.info['bads'] = []


trans = subjects_dir + '/' + subject + '/' + subject + '-trans.fif'
src = subjects_dir + '/' + subject + '/' + subject + '-ico4-src.fif'

bem = subjects_dir + '/' + subject + '/' + subject + '-5120-bem-sol.fif'


fwd = mne.make_forward_solution(raw.info, trans=trans, src=src, bem=bem,

meg=True, eeg=False, mindist=5.0, n_jobs=2)


This crashes with the following message, unless I remove the bad channels
specification with raw.info['bads'] = []

Traceback (most recent call last):

Do you have a solution?
Many thanks!
