VarSifter

VarSifter facilitates analysis, filtering, and visualization of sequence variation from massively parallel DNA sequencing experiments to support interpretation of exome-scale variant datasets.

Key Features:

• Sequence sorting and filtering: Performs sorting and multi-layer filtering of exome-scale variation datasets.
• Data compatibility: Accepts tab-delimited text files with headers and uncompressed VCF (Variant Call Format) files.
• Customizable filtering: Provides predefined filters and a custom query framework to filter by any combination of sample-specific or annotation-related criteria.
• Data visualization: Supports visualization of complex exome-scale sequence variation data for interpretation.
• Massively parallel sequencing support: Handles data derived from massively parallel DNA sequencing technologies and exome-scale experiments.

Scientific Applications:

• Genetic studies: Enables filtering and prioritization of variants for gene-centric and cohort-based genetic analyses.
• Disease-associated variant discovery: Facilitates identification and examination of candidate disease-associated variants from exome data.
• Population genetics: Supports comparative analyses of variant frequency and distribution across samples for population genetics studies.
• Personalized medicine: Assists variant prioritization workflows for patient exomes in personalized medicine applications.
• Evolutionary biology: Enables comparison and filtering of sequence variation for evolutionary analyses.

Methodology:

Accepts annotated input datasets and applies multiple layers of filtering and sorting operations using predefined filters and a custom query framework to extract variants based on sample-specific or annotation-related criteria.
