Hi,

I'm trying to import a bdf file using the mne_edf2fiff function and have 
run into two problems.

1) I don't have a proper elp or hpts file. Can someone please share or 
let me know how the information provided by Biosemi 
(http://www.biosemi.com/headcap.htm) can be converted properly?

2) I don't get an error message when I load the converted fif into 
mne_browse_raw. However, the display window remains empty.

Thanks!
Annett
