**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, collects the output, and throws away all the temporary files. It also produces a tab file with contig names, length and coverage.

Original wrapper developed by Lionel Guy.

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

Nicola Soranzo fixed various bugs.

Simon Gladman added fastg optional outputs.
