Before I do this myself...
Is there any compiled batch-corrected dataset of the major scRNA-seq atlases (Mouse Cell Atlas, Mouse Organogenesis Atlas, Mouse Gastrulation Atlas, Tabula Muris, Tabula Muris Senis, etc.) with processed spliced AND unspliced count matrices?
I would be surprised if there is, but in the event there isn't, are there new pipelines in development that will make processing of raw data easier for studying RNA velocity?
