Smalt

Smalt aligns DNA sequencing reads to reference genomes for next-generation sequencing (NGS) analyses and processes reads from various sequencing platforms, though it does not support SOLiD reads.

Key Features:

• Alignment Efficiency: Ranks second only to BWA for alignment speed in a benchmark of five microbial genomes, indicating competitive throughput for large datasets.
• Read Sensitivity and Pairing: Exhibits high sensitivity when mapping reads longer than 100 bp and maintains a high percentage of properly paired reads.
• Benchmark Evaluation: Was compared with BWA, Bowtie2, NovoAlign, and Stampy for sensitivity, mapping time, and handling of tandem repeats that can lead to incorrect mappings.
• Application in HTS: Performs mapping of reads onto reference sequences within high-throughput sequencing (HTS) workflows to support downstream genomic analyses.

Scientific Applications:

• Genomic Research: Provides read alignments required for downstream analyses such as variant detection and genome assembly.
• Medical Diagnostics: Supports identification of genetic mutations through accurate mapping of sequencing reads to aid diagnosis and personalized treatment strategies.

Methodology:

Performs alignment of DNA sequencing reads to reference genomes, reporting mapping coordinates and proper pairing, with optimization for reads >100 bp; it does not support SOLiD reads.
