[Mne_analysis] importing EGI Net Station EEG data into MNE

[Jeff Eriksen]

Alex,

Looking at mne_ex_read_write_raw, perhaps I am getting an inkling of what
to do now. I am confused by the use of "raw" in this script and indeed the
whole manual. What does "raw" mean? My definition would be just a 2D array
of EEG with no other information. But it appears that this example reads
and writes to fif files, so I will just guess that these routines will
work for me. Assuming I already have my EEG array in memory, I would then
use the following to write the data to a fif file: (??)

[outfid,cals] = fiff_start_writing_raw(outfile,raw.info,picks);
      fiff_write_int(outfid,FIFF.FIFF_FIRST_SAMPLE,first);
    fiff_write_raw_buffer(outfid,data,cals);
fiff_finish_writing_raw(outfid);

It appears that I will also need to define picks, using

        picks = 
fiff_pick_types(raw.info,want_meg,want_eeg,want_stim,include,raw.info.bads)
;

I will read up on these individual routines to see it they do what I
expect.




Let me know if I am on the right track,
-Jeff
