T-3: Continuing the analysis pipeline

Continuing my analysis pipeline in mne¶

# convert MEG data from CTF to .fif format
mne_ctf2fiff --ds /data/users/alanData/SPM-face/MEG/SPM_CTF_MEG_example_faces2_3D.ds/ \
    --fif /data/users/alanData/SPM-face/MEG/SPM_CTF_MEG_example_faces2_3D.fif

mne_ctf2fiff --ds /data/users/alanData/SPM-face/MEG/SPM_CTF_MEG_example_faces1_3D.ds/ \
    --fif /data/users/alanData/SPM-face/MEG/SPM_CTF_MEG_example_faces1_3D.fif

# setup the source space
mne_setup_source_space

That all went well, and then I hit my first snag¶

I've sent pretty much this exact message to the mne_analyze listserv, and we'll see how to resolve this.¶
