Question: Can I select more than 300 channels as excluded channels?

[SakimiNagashima]

Hello.
I am a master's student majoring in neuroscience in Japan.

I recorded neural activity using Neuropixels1.0 (384 channels, covering a wide range of the brain). I would like to analyze only the deepest 0–50 channels, so in the Kilosort4 GUI, I set channels 50–384 as excluded channels.

However, after spike sorting, when I check the results in Phy, I still detect spikes from channels 50–384.

Could you please let me know if I might have made a mistake in the exclusion settings or if there is another factor I should check?

Thank you for your help.

Best regards.

Please start by uploading kilosort4.log from the results directory. A screenshot of the kilosort GUI after loading your data would also be helpful.
