How can I convert data generated by Kilosort into a file readable by NeuroExplorer?

[AmaliaLambertRinguet]

Hi everyone,

We recently installed Kilosort4 and Phy2, respectively, to automate and manually refine the spike sorting.

Until now, we've been using Offline Sorter and directly exporting the sorted files as .nex to read them with NeuroExplorer.
We tried converting the .npy files generated by Kilosort to a .mat, but error messages appeared when attempting to open it with NeuroExplorer. We already solved the "Unable to get"... "TIME_UNITS", "Absolute time" but now we have "Unable to get Data matrix"...

Has anyone successfully converted Kilosort-generated data into a format compatible with NeuroExplorer? If so, could you please share the steps or recommend any tools or scripts that might help?

Thanks!

Hello,

I'll just mention briefly that we do not have any plans to add support for this to Kilosort4 and our development team does not have experience using that software. However, I will leave the issue open for a while in case other users have some answers for you.

If you need more information about the formats the results are saved in, refer to the documentation for kilosort.io.save_to_phy here: https://github.com/MouseLand/Kilosort/blob/main/kilosort/io.py
