Trouble running HS on Spikeinterface

[nasnass]

Hi! I am having a bit of difficulties getting HS to run using Spike interface. This is the error I am getting:

The extractor was not dumpable Error running herdingspikes Traceback (most recent call last): File "C:\Users\nasya\anaconda3\envs\herdingspikes\lib\site-packages\spikeinterface\sorters\basesorter.py", line 200, in run_from_folder SorterClass._run_from_folder(output_folder, sorter_params, verbose) File "C:\Users\nasya\anaconda3\envs\herdingspikes\lib\site-packages\spikeinterface\sorters\herdingspikes\herdingspikes.py", line 170, in _run_from_folder recording = st.normalize_by_quantile( File "C:\Users\nasya\anaconda3\envs\herdingspikes\lib\site-packages\spikeinterface\toolkit\preprocessing\normalize_scale.py", line 196, in normalize_by_quantile return NormalizeByQuantileRecording(*args, **kwargs) File "C:\Users\nasya\anaconda3\envs\herdingspikes\lib\site-packages\spikeinterface\toolkit\preprocessing\normalize_scale.py", line 60, in init random_data = get_random_data_chunks(recording, **random_chunk_kwargs) File "C:\Users\nasya\anaconda3\envs\herdingspikes\lib\site-packages\spikeinterface\toolkit\utils.py", line 36, in get_random_data_chunks for segment_index in range(recording.get_num_segments()): AttributeError: 'NoneType' object has no attribute 'get_num_segments'

Here is how I am running it:

sorting_HS = ss.run_herdingspikes(recording, output_folder='results_HS', filter=False, verbose=True)

Whenever I try to pre-process it, and then run the sorter, the Kernel dies.

recording_f = st.bandpass_filter(recording, freq_min=100, freq_max=3000) recording = recording_f.save(format='binary')

I have only take a small chunk of my data (not even 1GB) just to try and get it to work. Would be very thankful for any hints!

From your log it seems that the issue comes from SpikeInterface's preprocessing, have you tried submitting the problem to them ?

Just submitted it - thank you for the fast reply! I will comment the solution and close the issue here when I figure out what the problem is.

Just to check, has this been resolved?

[nasnass]

Sadly not

Can you run another sorter? It indeed looks like there is something wrong with the extractor, as pointed out by @BptGrm.
