QualitySNPng

QualitySNPng detects single nucleotide polymorphisms from RNA-seq and genomic DNA generated by next-generation sequencing using a haplotype-based, reference-independent approach and provides SNP visualization for downstream analyses.

Key Features:

• Haplotype-based detection: Uses a haplotype-based strategy to distinguish true SNPs from sequencing errors.
• Reference-independent analysis: Identifies SNPs without requiring a sequenced reference genome, enabling cross-species analysis.
• Input formats: Accepts SAM and ACE file formats as input.
• Sequencing support: Processes RNA-seq data and genomic DNA from next-generation sequencing technologies.
• Error filtering: Implements multiple filtering options to manage common sequencing errors and produce high-quality SNP calls.
• Ploidy support: Applicable to both diploid and polyploid organisms.
• SNP visualization: Generates visual representations of SNPs to facilitate inspection and interpretation.
• SNP array suitability: Produces high-quality SNPs suitable for SNP array development.

Scientific Applications:

• Genotyping by sequencing (GBS): Detects SNPs from GBS datasets for genotypic profiling.
• Genotyping: Provides SNP calls usable for genotyping applications.
• QTL mapping: Supplies SNP markers for quantitative trait loci mapping studies.
• GWAS: Generates variant sets applicable to genome-wide association studies.
• SNP array development: Identifies high-quality SNPs that can be used to populate SNP arrays.

Methodology:

Applies a haplotype-based SNP detection strategy on SAM and ACE inputs from RNA-seq or genomic next-generation sequencing data, with multiple filtering options to manage sequencing errors and produces SNP visualizations; performs reference-independent SNP identification.
