RT Journal Article SR Electronic T1 Benchmarking of lightweight-mapping based single-cell RNA-seq pre-processing JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.01.25.428188 DO 10.1101/2021.01.25.428188 A1 Booeshaghi, A. Sina A1 Pachter, Lior YR 2021 UL http://biorxiv.org/content/early/2021/03/03/2021.01.25.428188.abstract AB We compare and benchmark the two lightweight-mapping tools that have been developed for pre-processing single-cell RNA-seq data, namely the kallisto-bustools and Salmon-Alevin-fry programs. We find that they output similar results, and to the extent that there are differences, they are irrelevant for downstream analysis. However, the Salmon-Alevin-fry program is significantly slower and requires much more memory to run, making it much more expensive to process large datasets limiting its use to larger servers.Competing Interest StatementThe authors have declared no competing interest.
