Help extracting spikes (MUA) from LFP recorded with openephys

Hi all,
I am trying to use brainstorm to extract MUA from LFPs recorded with openephys (in openephys format, not binary). Is there a way to import my data so that the spike sorting works? For now, I keep getting the error "** Error: Error: Data type mismatch.** Invalid inputs for process:** "WaveClus"";
THanks in advance for any help with that!

The error you have seems to indicate you have importing your recordings to the database with the menu "Import MEG/EEG" instead of linking them with the menu "Review raw file".
I recommend you start by following all the introduction tutorials (section "Get started") and then the e-phys tutorials.
