Question: What version of STAR is used in Cell Ranger?
Answer: Cell Ranger 5.0.0 and above versions use STAR 2.7.2a, while Cell Ranger 4.0.0 and earlier uses STAR 2.5.1b. Since all the downloads are self-contained, you can find the current version in your downloaded package, for example, cellranger-x.y.z/STAR/2.5.1b. Also Cell Ranger v4 and above uses a modified version of STAR for performing the transcriptome alignment. Please refer to the release notes page here for more details.
