123VCF

123VCF filters genetic variants in Variant Call Format (VCF) files generated from Next-Generation Sequencing (NGS) data to support identification of clinically relevant and disease-associated variants.

Key Features:

• VCF File Processing: Processes both compressed and uncompressed Variant Call Format (VCF) files for genomic variant analysis.
• Disk-Streaming Filtering Algorithm: Applies a disk-streaming real-time filtering algorithm to analyze large variant datasets.
• Customizable Filtering Parameters: Supports filtering based on parameters including quality scores, coverage depth, and population variant frequency.
• User-Defined Filtering Rules: Enables application of custom filtering criteria tailored to specific research or clinical case requirements.
• Java-Based Implementation: Implements variant filtering within a Java framework for processing genomic datasets.
• Algorithmic Performance Comparison: Demonstrates runtime performance comparable to BCFtools filter and GATK VariantFiltration.

Scientific Applications:

• Disease Variant Identification: Supports identification of potentially pathogenic variants from Next-Generation Sequencing datasets.
• Medical Genetics Research: Facilitates analysis of genetic variants associated with inherited and complex diseases.
• Genomic Variant Analysis: Enables filtering of large variant datasets to prioritize variants for downstream genomic and clinical studies.

Methodology:

The tool processes compressed or uncompressed VCF files using a disk-streaming real-time filtering algorithm and applies user-defined filters based on quality scores, coverage depth, and population variant frequency.
