Yes, the linked OSCA workflow. scRNA-seq is a difficult analysis with a lot of things you have to know and many pitfalls. Please do not have the illusion that you can ‚simply and quickly‘ go through a prescripted analysis especially if you are new to bioinformatics, it will take time and a lot of reading and trying-out until you have a solid analysis result that you can stand-up for and confidently present. I recommend not no start with single-cell data and try something else like bulk RNA-seq first for practice since this is easier to digest. Also the size of single-cell datasets simply requires longer runtimes and more memory for most analysis strategies so it simply takes longer to repeat things of something goes wrong. Try some bulk RNA-seq first to get a feel and to get a background in bioinformatics. There are many online resources please google for it.
