Thanks. I'm on holidays right now but we can discuss that during the wired meeting next week ! SC2 is almost there, but clearly on some data, a too low threshold is not appropriate. Plus be careful, you might have the issue of negative gain, also not handled yet by SC2 if using neuralynx data
Hi spikeinterface team, and hi @yger,
I was using SpykingCircus2 on a recording I know and I know that the spike activity is very clean with a good SNR.
However, the results of the sorter are weird :
A lot of spikes are missed, detected on another channel than the one with very nice activity as you can see on the phy output... Even the spikes waveforms seems to not be centered.
I ran the sorter on a bandpass filtered recording between 300 and 6000Hz and I switched apply preprocessing in the parameters to false. I even tried with Zscore normalization and I get the same results.
Here are my parameters :
I can of course provide the data preprocessed : https://instituteicm-my.sharepoint.com/:f:/g/personal/anthony_pinto_icm-institute_org/EqcA_QR5nHREvj6YmWYim9gBLswTlFfomyn6vbOUT2W-pw?e=x2Ju8u
The threshold of detection was set automatically to : 3.403147543800265
Thank you in advance, Anthony
