SPAdes is a versatile toolkit designed for assembly and analysis of sequencing data. SPAdes is primarily developed for Illumina sequencing data, but can be used for IonTorrent as well. Most of SPAdes pipelines support hybrid mode, i.e. allow using long reads (PacBio and Oxford Nanopore) as a supplementary data.
SPAdes package contains assembly pipelines for isolated and single-cell bacterial, as well as metagenomic and transcriptomic data. Additional modes allow to discover bacterial plasmids and RNA viruses, as well as perform HMM-guided assembly. Besides, SPAdes package includes supplementary tools for efficient k-mer counting and k-mer-based read filtering, assembly graph construction and simplification, sequence-to-graph alignment and metagenomic binning refinement.

-
SPAdes assembler supports:
- Assembly of second-generation sequencing data (Illumina or IonTorrent);
- PacBio and Nanopore reads that are used as supplementary data only.
-
SPAdes allows to assemble genomes, metagenomes, transcriptomes, viral genomes etc.
-
Download SPAdes binaries for Linux or MacOS here. You can also compile SPAdes from source (requires g++ 9.0+, cmake 3.16+, zlib and libbz2). SPAdes requires only Python 3.8+ to be installed.
-
Test your SPAdes installation by running
bin/spades.py --test
- A single paired-end library (separate files, gzipped):

Standalone tools in SPAdes package: k-mer counting, k-mer cardinality estimation, k-mer-based read filtering, assembly graph construction, assembly graph simplification, alignment of long reads to an assembly graph, refinement of metagenomic binning.
If you use SPAdes in your research, please cite our latest paper.
In case you perform hybrid assembly using PacBio or Nanopore reads, you may also cite Antipov et al., 2015. If you use multiple paired-end and/or mate-pair libraries you may additionally cite papers describing SPAdes repeat resolution algorithms Prjibelski et al., 2014 and Vasilinetc et al., 2015.
