# polya_liftover - sc/snRNAseq Snakemake Workflow A [Snakemake][sm] workflow for using PolyA_DB and UCSC Liftover with Cellranger. Some genes are not accurately annotated in the reference genome. Here, we use information provide by the [PolyA_DB v3.2][polya] to update the coordinates, then the [USCS Liftover][liftover] tool to update to a more recent genome. Next, we use [Cellranger][cr] to create the reference and count matrix. Finally, by taking advantage of the integrated [Conda][conda] and [Singularity][sing] support, we can run the whole thing in an isolated environment. Please see our [README][readme] for the full details!
