Unrecognized function or variable "extract_spikes"

[Idavr]

Hi!

I am trying to run KS3 for the first time, and I ran into issues during the "extracting spikes for clustering" stage with this error:

Unrecognized function or variable 'extract_spikes'.

Error in ksGUI/runSpikesort (line 786)
[obj.rez, st3, tF] = extract_spikes(obj.rez);

Error in ksGUI/runAll (line 628)
obj.runSpikesort;

Error in ksGUI>@(,)obj.runAll() (line 319)
'Callback', @(,)obj.runAll());

Error while evaluating UIControl Callback.

I updated Kilosort right before running this as I noticed there had been some changes done, but there still seems to be something missing in the code I have or am I reading the error wrong?

Hello,
I am having a similar issue:

Undefined function or variable 'extract_spikes'.

Error in ksGUI/runSpikesort (line 786)
[obj.rez, st3, tF] = extract_spikes(obj.rez);

Error in ksGUI>@(,)obj.runSpikesort() (line 337)
'Callback', @(,)obj.runSpikesort());

Error while evaluating UIControl Callback.

Thanks.

The function is here: https://github.com/MouseLand/Kilosort/blob/main/clustering/extract_spikes., and it should be in your Matlab path. Could it be that you added an old version of Kilosort to the path instead?

Thank you. Yep, that was probably the reason. The folder clustering was not in my Matlab path.

Thank you @marius10p , it does indeed seem like this was the reason. All good now :)
