biased against narrow wave-shape spikes?

[esiabri]

Hi,
thank you for this amazing tool!
I've noticed that it seems that the narrow wave-shape spikes (coming from putative FS neurons) are more probable to be missed. I have attached here two sample snapshots from the Kilosort GUI, as it can be seen spikes with lower amplitudes were detected while larger narrower spikes are missed. I was wondering if I miss something and I can fix this through some parameters? does it have something to do with the fact they are less probable to be detected on multiple channels?
this is with kilosort 3 btw

It might be that the optimization did not find a single-channel fast spike template. Could you please try to plot wTEMP for this recording? There should be 6 traces, and one of those should be a fast spike.

yes, that's correct
