[Mne_analysis] more details on attempt to associate raw data with coordinate xform

[Jeff Eriksen]

I found mne_show_fiff, and verified that gsn257-trans.fif has a reasonable
looking xform matrix inside, and the EEG file, A1_smpl_raw.fif has the EEG
data as well as the electrode coordinates. So I still do not understand
why I get the error message below.

Thanks,

-Jeff
