chromDraw

chromDraw visualizes karyotypes in linear and circular formats to facilitate interpretation of chromosomal collinearity and rearrangements across species.

Key Features:

• Implementation: Implemented as an R package.
• Dual Visualization Modes: Produces both linear and circular representations of karyotypes.
• Output formats: Exports graphical outputs in EPS and SVG formats.
• Data compatibility: Accepts a proprietary input format compatible with the GenomicRanges data structure and can visualize BED files.
• Consistent input matrix: Uses a single, consistent input data matrix to ensure linear and circular karyotypes are generated from the same underlying data.

Scientific Applications:

• Comparative genomics: Visual comparison of karyotypes to depict shared collinearity and chromosomal rearrangements across species.
• Evolutionary biology: Analyses of chromosome-level changes relevant to evolutionary studies and speciation.
• Cytogenetics: Visualization of karyotype structure and rearrangements for cytogenetic investigations.

Methodology:

Generates linear and circular karyotype visualizations from a consistent input data matrix and accepts input compatible with the GenomicRanges data structure or BED files.
