This blog post deals with the various ways of downloading large amounts of sequencing data (e.g., from NCBI’s SRA database). When I needed to bulk download short read for a recent project, it took me some time to figure out how to achieve this efficiently, and I am sharing my experience here in the hope it might be useful.
The problem: you want to download lots of sequencing data (typically in form of Illumina generated reads), e.g., to reproduce a published experiment. The amount of data makes it impossible to click+download through a browser interface. There are two potential solutions: 1) download via NCBI’s SRA toolkit, and 2) access ftp servers directly.
