how to tell Kilosort some channels are bad, do not use them?

Hi,
How to tell Kilosort some channels are bad, do not use them?
Thank you

I'm also interested in this feature, it looks like it is possible to create a probe object and set dead channels to -1 (see last block in): https://github.com/MouseLand/Kilosort/blob/main/docs/tutorials/load_data.ipynb

I'm going to find some time soon to try this out

There is not currently a way to specify this separate from the probe file you use, so you would have to save a new copy of it with those channels excluded. For example, if I originally use:

n_chan_bin = 64
probe = {'chanMap': np.arange(64), ... <other entries specifying 64 values>}

and then notice that the first 3 channels in the data are bad, I would instead use:

n_chan_bin = 64  # this doesn't change
probe = {'chanMap': np.arange(3, 64), ... <other entries specifying 61 values>}
