Creating figures without displaying them?

Dear mne experts,

I am trying to create figures without displaying them.

I have used Agg as follows:

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

ica.plot_sources, ica.plot_overlay and ica.plot_scores seem to work
correctly.

However, "fig = stc.plot(surface='inflated', hemi=hemi,
subjects_dir=subjects_dir, figure=i)" gives "ipython: cannot connect to X
server".

Any ideas what might be wrong?

Best,
Maria

hi Maria,

stc.plot uses mayavi and opengl and not matplotlib.

to use it in "headless" mode ie without an x server see:
