dottup

dottup generates wordmatch dotplots that visualize alignments between two nucleotide or protein sequences to identify regions of local similarity and is part of the European Molecular Biology Open Software Suite (EMBOSS).

Key Features:

• Dotplot Visualization: Produces wordmatch dotplots that display matching subsequences between two sequences to reveal local similarities.
• Wordmatch Algorithm: Implements a wordmatch algorithm to detect matching words (subsequences) between sequences.
• EMBOSS Integration: Functions as a component of the European Molecular Biology Open Software Suite (EMBOSS).
• Extensible C Libraries: Uses EMBOSS C programming libraries to enable extension and development of additional bioinformatics functionality.

Scientific Applications:

• Sequence Comparison: Compares genomic or proteomic sequences to identify regions of similarity that may reflect functional or evolutionary relationships.
• Mutation Analysis: Visualizes alignments to detect mutations and assess their potential impact on protein function or gene regulation.
• Structural Biology: Highlights conserved regions and structural motifs across species or within protein families to inform structural studies.

Methodology:

Generates dotplots by plotting one sequence along each axis and marking points where subsequences ("words") match using a wordmatch algorithm.
