Issues with too many noisy channels

[yunchang-z]

Hi! I am trying to apply ibl sorter on my dataset and I kept getting a "More than half of channels are considered bad. Verify your raw data and eventually update" error. My data were clean (there was no visible 60 Hz noise in the raw traces and the RMS was very low ~20 uv when I turned on glbdmx in Spikeglx).

If I tried to bypass this error by raising the psd_hf_threshold parameter to 0.04, the program starts to give me warning messages as below:

"...\iblenv\lib\site-packages\ibldsp\voltage.py:299: RuntimeWarning: invalid value encountered in divide
weights = weights / gp.sum(weights)"

and

"...\envs\iblenv\lib\site-packages\dartsort\peel\threshold.py:100: UserWarning: 47972 spikes in chunk was larger than self.max_spikes_per_chunk=40000. Keeping the top ones."

I am wondering if you guys have thoughts on this. Could it be because my mouse was freely moving and there was just more noise?

Thank you!

Best,
