The first publicly available, standalone genome sequence scaffolding program. It orders and orients contigs into scaffolds based on various types of linking information. |
Bambus 2.0, the second generation Bambus scaffolder available as an open source package. While most other scaffolders are closely tied to a specific assembly program, Bambus accepts the output from most current assemblers and provides the user with great flexibility in choosing the scaffolding parameters. In particular, Bambus is able to accept contig linking data other than specified by mate-pairs. Such sources of information include alignment to a reference genome (Bambus can directly use the output of MUMmer), physical mapping data, or information about gene synteny. |
An ultrafast, memory-efficient short read aligner that aligns short DNA sequences to the human genome at a rate of about 25 million reads per hour on a typical workstation with 2 GB of memory. Bowtie indexes the genome with a Burrows-Wheeler index to keep its memory footprint small: 1.1 GB for the human genome. Steven Salzberg has been nominated for the 2013 Benjamin Franklin Award in the Life Sciences. This is a humanitarian/bioethics award presented to an individual who has, in his or her practice, promoted free and open access to the materials and methods used in the life sciences. More information on the award can be found at http://www.bioinformatics.org/franklin/. |

A whole genome assembler originally developed at Celera Genomics for the assembly of the human genome. CeleraAssembler is now an open-source project at SourceForge. The code is actively maintained by researchers at CBCB and the Venter Institute (formerly known as TIGR, The Institute for Genomic Research). |
(New in Nov 2008) Highly Sensitive Short Read mapping with MapReduce. CloudBurst uses Hadoop - an open source version of Google's parallel computing software MapReduce - to efficiently parallelize the short read mapping problem to dozens or hundreds of computers. This enables CloudBurst to execute highly sensitive read mappings with any number of mutations or indels. |
(New in Nov 2009) Crossbow is a scalable software pipeline for whole genome resequencing analysis. It combines Bowtie, an ultrafast and memory efficient short read aligner, and SoapSNP, an accurate genotyper, within Hadoop to distribute and accelerate the computation with many nodes. The pipeline can accurately analyze over 35x coverage of a human genome in one day on a 10-node local cluster, or in 3 hours for about $100 using a 40-node, 320-core cluster rented from Amazon's EC2 utility computing service. |

A visual analytics tool for genome assembly analysis and validation, designed to aid in identifying and correcting assembly errors. All levels of the assembly data hierarchy are made accessible to users, along with summary statistics and common assembly metrics. A ranking component guides investigation towards likely mis-assemblies or interesting features to support the task at hand. Can be used to interactively analyze assemblies from many popular assemblers on your desktop computer. See the journal paper here. |

R package to estimate differential abundance of marker gene survey data and visualize results. |
Metagenomic datasets prove challenging to assemble using traditional assembly pipelines designed for individual genomes. Using AMOS as a foundation, we have created a robust & easy-to-use metagenomic assembly pipeline that takes reads (FASTA,FASTQ,SFF) and assembles them into Unitigs (CABOG,NEWBLER,Minimus,SOAPdenovo), Contigs & Scaffolds (Bambus2) & ORFs (Glimmer MG, MetaGeneMark), and annotates results using Metaphyler and a graph-based propagation method. MetAMOS was designed with efficiency in mind and can run through tens of millions of reads in a few hours on a multi-core workstation with ample RAM. |

High throughput sequence alignmentusing Graphics Processing Units (GPUs). Uses a technique called general-purpose GPU programming (GPGPU programming) to harness the extreme parallelism of GPUs for non-graphics tasks. In this application, hundreds of query sequences are simultaneously aligned to a reference sequence, creating an order of magnitude speed up over the same alignmenton the CPU. |
