Double Counting shifted spikes

Open congcong96 opened this issue 3 years ago • 1 comments

It seems somehow, the spikes are shifted in time and double counted. You can tell by the overlay of the waveform and the peak at 0 in CCG. Not sure hoe did this happen. As only a subset of the spikes are double counted and the blue one has lower amplitude, my guess is that after subtracting the spike from the trace, a little bump is detected around the original spike.

You are describing the same issue previously discussed here: https://github.com/MouseLand/Kilosort/issues/29

There is no perfect solution, but that thread provides some workarounds.
