How to remove nose and ears from Topomap image ?

[ddaschakladar (Debashis)]

Hi,
I am using mne.viz.plot_topomap() for generating topomaps. For my experimental analysis, I need the topomaps without nose and ears. Surprisingly, for other EEG data with same code, the generated topomap does not contains the ears and nose. But for another EEG dataset, the same code produces the ears and nose. My code for generating the topomap is given below:
fig = evoked.plot_topomap(
times=[max_gfp_time],
show=False,
colorbar=False,
size=4, # Control the size of the head in the plot
res=300, # Increase the resolution of the topomap
contours=0,
sphere=(0., 0., 0., 0.09)
)

Any help is highly appreciated !!

Thanks

This should be possible with outlines=None (the default is outlines="head") (see mne.Evoked — MNE 1.8.0 documentation).

Thanks for the response. But it did not work as I attached the output image after changing your suggestion.
