[Mne_analysis] Problem using mne_analyze

[Peter Glynn]

Hi,

I am new to MNE (and linux) and I am running through the sample data set for
practice. Everything seemed to be working fine until I had to use
mne_analze. I loaded the digitizer data from the sample_audvis_raw.fif file,
and got a message saying that 146 digitizer points had been loaded from the
file. But nothing was brought up in the gui besides this message, so I'm not
sure this step worked completely. When I went to load the inflated surface,
a message appears in the gui saying "No data loaded" and the following
appears in the terminal window:

Loading surface

Any ideas as to what the problem is? When would the T1.mgz file have been
generated/modified? Was my download incomplete from the beginning? Any help
would be much appreciated! Thanks!
