The data are fetched from SPAdes-3.5.0 source tarball (subdir test_dataset).

The original sga test was run on the data that could be downloaded via

wget http://ftp.sra.ebi.ac.uk/vol1/fastq/SRR065/SRR065390/SRR065390_1.fastq.gz
wget http://ftp.sra.ebi.ac.uk/vol1/fastq/SRR065/SRR065390/SRR065390_2.fastq.gz

but be warned:  The 2x2.1 GB download should be considered seriously since
you need some quite performant hardware to run the test in less than 12 hours.
