**What it does**

SPAdes – St. Petersburg genome assembler – is intended for both standard isolates and single-cell MDA bacteria assemblies. See http://bioinf.spbau.ru/en/spades for more details on SPAdes.

This wrapper runs SPAdes 3.9, collects the output, and throws away all the temporary files. It also produces a tab file with contig names, length and coverage.

Anton Korobeynikov greatlty helped understanding how SPAdes work, and integrated handy features into SPAdes.

Nicola Soranzo fixed various bugs.
