RNA STAR Solo, to many cells?

Question

[ju_ra]

Hi guys,

I am trying to map online scRNASeq Data to the murine genome using STAR (Galaxy Version). Looking at my results I get the following output:

Barcodes:

Does anybody have an Idea why I get so many cells? As I understand it correctly yesCellBarcodes means the number of cells which were detected but 1561374 seems way to high...
