dotmatcher

dotmatcher generates threshold dotplots of two sequences to visualize regions of similarity for comparative sequence analysis.

Key Features:

• Threshold dotplot generation: Produces dotplots of two sequences with an adjustable threshold to highlight significant local similarities.
• Sequence alignment visualization: Represents alignments and repeat structures graphically to aid identification of conserved regions and similarity patterns.
• EMBOSS integration: Functions as a component of the EMBOSS suite, enabling interoperability with other EMBOSS applications and workflows.

Scientific Applications:

• Comparative genomics: Visualizes sequence similarity between genomic regions to support comparisons across organisms or loci.
• Evolutionary studies: Reveals conserved and rearranged regions that inform phylogenetic and evolutionary analyses.
• Functional genomics: Identifies conserved sequence motifs and structural similarities relevant to gene function and regulation.
• Detection of conserved regions and genetic variation: Highlights conserved blocks and discrepancies useful for studying genetic variation and structural differences.

Methodology:

Generates threshold-based dotplots of two sequences; implemented using the extensible C programming libraries of EMBOSS and configured via Application Configuration Description (ACD) files.
