<br>
I’ve run into a problem trying to import one of my subject recordings. It appears that the header labels do not match the config channels. This is the first subject I’ve seen this error in.<br>
<br>
I used the private functions mne.io.bti.bti._read_bti_header_pdf(raw_file) and mne.io.bti.bti._read_config(config_file). It looks like a handful of the channels are missing from the pdf (header). The error states “channels found are not described in config”, but it looks like the check is just for equality of channel numbers rather than directional. Intuitively, it seems like we should be able to import the data from the pdf itself even if it doesn’t have all of the system channels. Would it make sense to change the equality check to just make sure that all header channels exist in the config rather than vice versa? Or might that create other problems down the road? <br>
<br>
Error message below.<br>
<br>
Thank you,<br>
