ERNE

ERNE aligns Next Generation Sequencing (NGS) reads using an extended randomized numerical method to enable accurate mapping of bisulfite-treated reads for DNA methylation analysis.

Key Features:

• Alignment Accuracy: Implements an extended randomized numerical approach to improve precision of NGS read mapping.
• Bisulfite-Treated Reads Mapping: Optimized for bisulfite-treated reads, which convert unmethylated cytosines to uracil while methylated cytosines remain unchanged, enabling methylation status determination.
• Preprocessing Integration: Operates in workflows with read trimming preprocessing to remove low-quality bases and preserve high-quality segments, improving downstream analyses such as RNA-Seq, SNP calling, and genome assembly.

Scientific Applications:

• Gene Expression Quantification: Produces alignments suitable for RNA-Seq-based quantification of gene expression.
• Genotyping and SNP Calling: Provides read mappings appropriate for identifying single nucleotide polymorphisms (SNPs) and genotyping analyses.
• Genome Reconstruction: Supplies reliable alignments that support genome assembly from fragmented sequencing data.

Methodology:

Employs an extended randomized numerical alignment algorithm, explicitly handles bisulfite-induced cytosine-to-uracil conversions during mapping, and is used in conjunction with upstream read trimming preprocessing.
