[Mne_analysis] Inverse Operator error

[obregon at nmr.mgh.harvard.edu]

Hi,

When trying to compute the inverse solution on the sample data set, I'm
getting the following error prompt when the mne_do_inverse_operator
program is done running:

'/usr/pubsw/packages/mne/stable/bin/mne_do_inverse_operator: line 320: 
8678 Segmentation fault $inv_command
Inverse operator decomposition failed (see above)'

What does this message mean and how can this be fixed?

Thanks a lot,

Gabriel
