All EEG channels are not referenced to the same electrode when running the following code

I am using Version 1.9.0.

When I point fname to the sample file, I get the impedences.
cnt = read_cnt(fname)
_, _, _, impedances, _ = read_triggers(cnt)

I get an error with the same code when I point fname to my file.

When I continue with
raw = read_raw_ant(fname,preload=True)
pointing to my file or the sample file, I get the correct output.

Both Neuroscan and ANT Neuro use different file formats with the same .cnt extension. This means that the example file is a Neuroscan CNT and therefore requires read_raw_cnt(). Your file is an ANT Neuro CNT and therefore requires read_raw_ant().

Clemens,

I have been using read_raw_ant. I get a nice raw file that contains the data that I need.

During execution of read_raw_ant, I also get some warning messages. They don’t seem to affect my data but I always get nervous using new tools when I get warnings.

I loved a city once. It’s gone now. What’s left are the memories.
