Novoalign

Novoalign aligns short and long reads from Illumina, IonTorrent, and 454 next-generation sequencing platforms to reference genomes for accurate read mapping used in downstream analyses such as variant detection and RNA-seq.

Key Features:

• Versatility Across Platforms: Supports reads from Illumina, IonTorrent, and 454 sequencing platforms.
• High Sensitivity: Demonstrates high sensitivity mapping short reads (e.g., 36bp, 50bp, 72bp) and long reads (>100bp), including complex genomes such as Plasmodium falciparum.
• Proper Pairing of Reads: Aligns paired-end reads with emphasis on proper pairing to support accurate variant detection and transcript quantification.
• Benchmarking Performance: Has been benchmarked against aligners such as BWA and Bowtie2 for alignment time, sensitivity, and handling of tandem repeats, showing balanced performance across read lengths and genome complexities.

Scientific Applications:

• RNA-seq Analysis: Provides accurate alignments required as input for RNA-seq pipelines and downstream expression and splicing analyses.
• Genomic Research: Enables detection of polymorphisms and other genetic variation by mapping reads to reference genomes.
• Medical Diagnostics: Facilitates identification of clinically relevant genomic alterations through precise read alignment.

Methodology:

Novoalign employs an indexing strategy of the reference genome instead of building hash tables for reads.
