Noor (@noorpratap.bsky.social) has been working on this for quite some time! It took a bit of work to figure out, but now you can map your scATAC-seq reads directly to the genome and sort and dedup them with alevin-fry-atac. You get a BED file with counts ready for downstream analysis! 1/
Alevin-fry-atac enables rapid and memory frugal mapping of single-cell ATAC-seq data using virtual colors for accurate genomic pseudoalignment https://www.biorxiv.org/content/10.1101/2024.11.27.625771v1
