BUG: plot topographies

[kingjr]

Even if I apply the channel preprocessing hcp.preprocessing.map_ch_coords_to_mne(inst), some plotting functions crash into an unclear error if data channels aren't picked (i.e. inst.pick_types(mag='meg')):

import numpy as np
import hcp
import mne
raw = hcp.read_raw(run_index=1,
                   hcp_path='/home/jrking/Desktop/hcp',
                   subject='105923',
                   data_type='task_story_math')
epochs = mne.Epochs(raw, np.array([[0, 0, 1]]), tmin=0., tmax=2.000)
evoked = epochs.average()
hcp.preprocessing.map_ch_coords_to_mne(evoked)
evoked.plot_joint()  # crash
evoked.pick_types(meg='mag')
evoked.plot_joint()  # ok

Thanks for reporting I'll be back on mne-hcp soon.
Yes joint plot has a problem and it's partly due to mne. You may also need
the hcp variant of the layout, see helper in hcp.viz
