vcf_remove_filtered

vcf_remove_filtered removes filtered lines from Variant Call Format (VCF) files within the VCFtools suite to produce cleaned variant datasets for downstream genomic analyses including population genetics, association mapping, and evolutionary biology.

Key Features:

• Filtered record removal: Removes VCF records marked as filtered to retain only unfiltered variant calls.
• VCF variant types supported: Operates on VCF files containing single nucleotide polymorphisms (SNPs), insertions, deletions, structural variants, and associated annotations.
• Compatibility with large-scale datasets: Compatible with VCFs produced for projects such as the 1000 Genomes Project, UK10K, dbSNP, and the NHLBI Exome Project.
• Data compression and indexing: Supports working with compressed and indexed VCF files to enable efficient storage and rapid retrieval of variant data by genomic position.
• Galaxy integration: Integrated into the Galaxy platform for execution within reproducible computational workflows.
• API execution: Executable via the Galaxy API or the Bioblend library on high-performance computing clusters such as those at Institut Pasteur.

Scientific Applications:

• Population genetics: Producing cleaned variant call sets for allele frequency and population structure analyses.
• Association mapping: Generating high-confidence variant inputs for genome-wide association studies.
• Evolutionary biology: Preparing curated variant datasets for phylogenetic and evolutionary inference.

Methodology:

Removes filtered lines from VCF files; can be invoked within Galaxy or programmatically via the Galaxy API or Bioblend on high-performance computing clusters.
