Protocol for Fast Scrna-Seq Raw Data Processing Using Sckb and Non-Arbitrary Quality Control with COPILOT

We describe a protocol to perform fast and non-arbitrary quality control of sin-gle-cell RNA sequencing (scRNA-seq) raw data using scKB and COPILOT. scKB is a wrapper script of kallisto and bustools for accelerated alignment and tran-script count matrix generation, which runs significantly faster than the popular tool Cell Ranger. COPILOT then offers non-arbitrary background noise removal by comparing distributions of low-quality and high-quality cells. Together, this protocol streamlines the processing workflow and provides an easy entry for new scRNA-seq users.For complete details on the use and execution of this protocol, please refer to Shahan et al. (2022).
