isochore

isochore identifies and plots isochores—regions of DNA with distinct base composition—in genomic sequences to analyze genomic organization and evolution.

Key Features:

• Isochore detection and plotting: Identifies and plots isochores—regions with distinct base composition—within genomic sequences.
• Base-composition analysis: Performs computational analysis of base composition to detect regional variations across genomes.
• Integration with EMBOSS: Integrates with the EMBOSS suite for compatibility and interoperability with other EMBOSS applications.
• Extensible C programming libraries: Built on EMBOSS's extensive and extensible C libraries to enable programmatic access and extension.
• ACD-based customization: Supports customization through ACD (Application Configuration Description) files to modify application behavior.
• Portability and third-party integration: Allows wrapping and porting of third-party applications into EMBOSS workflows.

Scientific Applications:

• Genomic organization and evolution: Characterizes genomic organization and isochores to inform studies of genome structure and evolutionary patterns.
• Gene density and regulatory element mapping: Maps regions of distinct base composition that correlate with gene density and regulatory element distribution.
• Comparative genomics and evolutionary pressures: Enables comparative analyses across species to investigate evolutionary pressures associated with base-composition variation.

Methodology:

Computational analysis of genomic sequences to detect variations in base composition and plot isochores, implemented using EMBOSS C programming libraries, configurable via ACD files, and able to integrate with external databases and software packages.
