[Mne_analysis] topo plot

[Kirk Gregory R.]

Hi,

im trying to get tononi's lab set us using the mne tools, everything pretty
smoth exept the eeg geometry.

included a tiff of the topoplot the electrodes at the vertex ( top) of the head appear out at the boundary instead
rather than at the center. seems i remember something that it was supposed to work that way years
ago when i was there, or maybe i just need a memory circuit replaced ?

also the digitization data im using is from the nextstim optical system, the electrode positions did not
seem all to make sense, had a few on the bottom of the neck ? . the numbers are all less than 1.0 so i assumed that i needed to use the --meters option to
import the digitize data. i just make a .htps file out of the .elp file from nextstim as the .elp file was not recognizable by the mne import function, ie. 
seems the nextstim .elp was written by somebody with a different standard manual than matti cited in the doc and it seemed much easier to just
yank out the numbers and make a .htps


trying to get a movie of an auditory erp made as a some  people
from egi will be here tomorrow and i would like to show them, got the freesurfer processing
and bem surfaces made, forward model, import the eeg data fine and can compute an average,
so if i can just get a sensible mri->eeg coord tran i should be able to make a movie.

thanks

Greg
