Description

Hi all,

I'm using Kilosort2.5 for spike sorting 256 channels (128 + 2*64 probes - they are independent and in Kilosort channel map I set kcoord to 1,2,3). When I load kilosort output into phy, traceview doesn't seem to show me the correct channel map. Also shown traces don't seem to correspond to the mean waveforms in the waveform view. Please check the screenshot. I will appreciate if you could provide info on how to fix this.

Research direction

Reproduce the issue by loading Kilosort2.5 output for the 256-channel setup into phy and compare TraceView with the waveform view. Inspect how the configured channel map and kcoord values are interpreted; done means TraceView uses the correct channel mapping and its traces correspond to the mean waveforms.
