About cell anno in Part2

[mugpeng]

Hi,

It's a great work you've done and congratulate.

I notice in the annotation, you used singleR described as:

Part 2: The SingleR package v.1.4.1 (ref. [19](https://www.nature.com/articles/s41588-022-01141-9#ref-CR19)) was used with the Human Primary Cell Atlas database

And I find the reference is not a scRNA dataset, and it's a chip data of human primary cell.
Can you explain why you use chip data instead of scRNA data as reference, because I have never seen people used a non-scRNA data for singleR. And does it make a good sense?
Besides, I can't find the expression data in the reference article, could you serve it for me?

Thanks a lot, and waiting for you reply.
