VCF2CAPS

VCF2CAPS converts DNA sequence variants, including single nucleotide polymorphisms (SNPs), multi-nucleotide polymorphisms (MNPs), and insertion/deletion (indel) polymorphisms, into cleaved amplified polymorphic sequence (CAPS) markers for PCR-RFLP marker development and genotyping from next-generation sequencing (NGS) data.

Key Features:

• High-Throughput Conversion: Processes large datasets generated by next-generation sequencing (NGS) to convert SNPs, MNPs, and indels into CAPS markers.
• Comprehensive Variant Support: Supports conversion of SNPs, MNPs, and indels into CAPS markers.
• Restriction Endonuclease Identification: Identifies restriction endonucleases that recognize sequences containing SNPs, MNPs, or indels.
• Advanced Filtration Utilities: Selects markers with a single polymorphic cut site within a user-specified sequence length and differentiates up to three user-defined groups of individuals.
• Experimental Validation: Performance was tested using genotyping-by-sequencing (GBS) data with selected CAPS markers subjected to experimental verification.

Scientific Applications:

• PCR-RFLP marker development: Designs CAPS markers for PCR-RFLP assays across plant, animal, and human genetics.
• High-throughput genotyping: Generates markers for large-scale genotyping projects from NGS and GBS datasets.
• Molecular diagnostics: Produces CAPS markers applicable to molecular diagnostics and genetic analysis.

Methodology:

Converts DNA sequence variants (SNPs, MNPs, indels) into CAPS markers by identifying restriction endonuclease recognition sites overlapping variant-containing sequences, applying filtration for a single polymorphic cut site within a user-specified sequence length and for differentiation among up to three user-defined groups, and was tested on genotyping-by-sequencing (GBS) data.
