gdtools_mask

gdtools_mask filters mutation predictions in GenomeDelta (GD) files by excluding variants that overlap MASK-defined masked regions of the reference genome to produce a refined GD file for downstream genomic analyses.

Key Features:

• Masked Region Filtering: Creates a new GD file by excluding mutations from an input GD file that overlap masked regions specified by MASK entries in a mask GD file.
• Precision in Mutation Removal: Removes mutations only when they overlap exclusively with masked bases and do not intersect any unmasked bases, preserving variants in unmasked regions.

Scientific Applications:

• Computational biomedical research: Provides cleaner mutation datasets for computational biomedical research where accurate mutation data is critical.
• Comparative genomics: Improves comparative genomics analyses by removing variants in masked regions that could confound sequence comparisons.
• Evolutionary biology: Supports evolutionary biology studies by ensuring variant calls reflect unmasked genomic regions.
• Personalized medicine: Enhances variant filtering for personalized medicine by excluding mutations in predefined masked regions from analysis.

Methodology:

Accepts an input GD file containing mutation predictions; applies a mask GD file whose MASK entries define regions of the reference genome to exclude; outputs a GD file with mutations removed when they overlap solely with masked bases and not unmasked bases.
