Hello,
I found the idea of finding patterns and projecting them into similar datasets very promising in such a challenging part of scRNA-seq analysis as cell identification.

The function that was used there is called RunCoGAPS, but I can't find it in the package documentation. I have several questions about that function:
You can select either. Using all genes will increase run time but provide more information. Genes selected need to have non-zero variance for the algorithm to work.
Correct, normalized data.
They should be identical.
thank you, Yulia
