GenomeTools

GenomeTools provides an extensible C library and suite of programs for creating, processing, and converting annotation graphs to represent and manipulate genomic features and their subcomponents for genome informatics.

Key Features:

• Graph-Based Annotation Representation: Implements a strict annotation graph model to represent genomic features and their subcomponents.
• Efficient Data Processing: Implements a pull-based method for sequential processing of annotations to reduce memory overhead when handling large datasets, including catalogs of human genetic variation.
• Object-Oriented Design: Provides an object-oriented programming interface implemented in C for construction and manipulation of annotation graph objects.
• Memory Efficiency: C implementation minimizes memory footprint while supporting both sequential and random access to the annotation graph.
• Integration with Scripting Languages: Provides bindings for scripting languages including Python and Ruby.

Scientific Applications:

• Genomics: Management and processing of large genome annotation sets for genomics research.
• Transcriptomics: Representation and manipulation of transcript models and gene annotations in transcriptomics analyses.
• Personalized Medicine and Human Variation Analysis: Analysis of human genetic variation and support for applications in personalized medicine using large-scale annotation datasets.

Methodology:

Uses an annotation graph approach with a pull-based processing model that enables sequential processing and supports random-access queries.
