This component downloads reads from the SRA/ENA public databases from a list of accessions. First, it tries to use aspera connect to download reads, if a valid aspera key is provided. Otherwise it uses curl, which is substantially slower. The reads for each accession are then emitted through the main output of this component to any other component (or components) that receive FastQ data.
