Hi Matti,
I am still having issues using mne_kit2fif (see discussion below). I
can't get the triggers to show up. I can open the original data on
the KIT software and I can see the channels for the triggers fine.
When I export it to txt and use the mne_kit2fif command I don't get
any triggers. I tried using --add flag but this doesn't give me the
triggers, just flat lines.
The triggers were on channels 176, 177, 178, 179, 180 and I added 1
to each to convert to the mne system.
ANy suggestions would be appreciated.
Thanks
Mark
