About recording electrodes

[ohkoibln]

Hello, I would like to know how to identify which electrodes recorded the signal for each unit after obtaining units using Kilosort2?

@ohkoibln,

we have a variety of ways to get this information by calculating the unit_locations with your preferred method. You can see the methods here.

What version of spikeinterface are you using? If you are using from source or the 0.101.0.rcX then you would make a sorting analyzer and then compute to get these values.

This tutorial discusses how to calculate various value including locations for versions 0.100.8 and below. this tutorial does the same for the newer api for version 0.101.0.

Thanks but I already had the information of unit_locations, I need something else. For example, electrodes 4,7889,24457 recorded the signal of unit 4.

@ohkoibln， 我们有多种方法可以通过计算您喜欢的方法获取此信息。您可以在此处unit_locations查看方法。 您使用的是哪个版本的 spikeinterface？如果您使用的是源代码或 0.101.0.rcX，那么您可以制作一个排序分析器，然后计算以获取这些值。 本教程讨论了如何计算 0.100.8 及以下版本中的各种值（包括位置）。本教程对 0.101.0 版本的较新 API 执行相同操作。

谢谢，但我已经获得了 unit_locations 的信息，我需要其他信息。例如，电极 4,7889,24457 记录了单元 4 的信号。

I want to know more about every unit, Thanks!!

@ohkoibln It's a bit unclear what information you would like to know. Can you be more specific? Do you need a set of channels on which each unit appears?

If that's the case, you can get it from the analyzer sparsity:

print(analyzer.sparsity.unit_id_to_channel_ids)

[ohkoibln]

@ohkoibln不太清楚您想要了解什么信息。您能更具体一点吗？您需要一组每个单元出现的频道吗？

如果是的话，你可以从分析器稀疏度中获取它：

print(analyzer.sparsity.unit_id_to_channel_ids)

Gratefully thanks I think that is what I mentioned, Thanks a lot. May I learn more about every unit, Is there any unit guideline?

As Alessio said I don't think either of us are 100% sure what you are asking for. Do you want something different from what Alessio suggested or are you asking how to get that information for every unit?

正如 Alessio 所说，我认为我们俩都不能 100% 确定您的要求。您想要与 Alessio 建议的不同的东西吗，还是您问如何获取每个单元的信息？

Maybe I have got the information from the other replay concerning features. Thank you again!
