OGdraw

OGdraw generates high-resolution graphical maps of circular DNA sequences to visualize organellar genomes such as mitochondrial and plastid/chloroplast genomes from GenBank-formatted sequences for structural and comparative analysis.

Key Features:

• High-resolution map generation: Produces custom, high-resolution graphical maps of circular DNA sequences.
• GenBank input support: Accepts GenBank-format files and GenBank accession numbers as input.
• Organellar focus and generality: Optimized for mitochondrial and plastid/chloroplast genomes and applicable to any circular DNA sequence.
• Genome size range: Handles organellar genome sizes ranging from approximately 15 kilobases (kb) to over 2 megabases (Mb).
• Automated, standardized rendering: Generates automated, consistent graphical representations to avoid heterogeneity from semi-manual drawing.
• Perl module and modular architecture: Implemented as a Perl module with an object-oriented interface and modular architecture enabling integration into custom scripts.

Scientific Applications:

• Organellar genome visualization: Visualizes mitochondrial and plastid/chloroplast genome structures as graphical maps.
• Structural and comparative analysis: Supports structural visualization and comparison of circular genomes using GenBank-formatted sequences.
• Workflow integration: Enables programmatic incorporation of graphical map generation into custom bioinformatics scripts via its Perl module.

Methodology:

Implemented as a Perl module with an object-oriented interface and modular architecture that generates graphical maps from GenBank-format files or GenBank accession numbers.
