I am using data from the Tabula Muris Consortium.
These are gene counts from scRNA-seq of mouse cells.
There are some specific genes with name ending with suffix 'Rik' (e.g. 0610005C13Rik or 0610007C21Rik). Searching online I found that they are from RIKEN project.
However, they are different in some respects (e.g. antisense lncRNA gene, or mouse 0610007C21RIK Adenovirus).
I want to exclude them from downstream analysis, but it is unclear to me the main purpose of this collection. For which kind of analysis are they used?
