Dear List:
I used mne_forward_solution per the messages written which are listed below my signature. When I look in the output file, TestFwd.fif using mne_show_fiff I find no results. The output from that is shown at the bottom of this message. I truncated a couple of things but left what was before and after them to show that they do not include the forward solution results.
Any thoughts or suggestion would be most appreciated. Thanks.
