bdf import issue

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

Hi Annett,
    The following is a hpts version of the standard 64 channel Biosemi layout (and also includes standard cardinal point locations) which you could download and provide for the hpts argument when importing...
https://github.com/mne-tools/mne-python/blob/master/mne/io/edf/tests/data/biosemi.hpts

Regarding, not being able to see the channels, I think you just need to add your channel names (probable A1-32 and B1-32) to the channel selection...it seems like the data were imported successfully. You could do that from the channel selection drop down menu of mne_browse_raw and using "Add.." button.

HTH,

This is the same file with the Bio semi names rather than the 10-20 names:
