Chromatiblock

Chromatiblock visualizes the presence, absence, and arrangement of syntenic (colinear) blocks across collections of complete bacterial genomes to support comparative and structural genomic analyses.

Key Features:

• Synteny visualization: Illustrates synteny by mapping colinear conserved DNA blocks across multiple bacterial genomes.
• Representation of presence/absence and arrangement: Displays presence, absence, and genomic arrangement of syntenic blocks to reveal genomic rearrangements.
• Scalability: Supports whole-genome comparisons across large collections of bacterial genomes and large-scale datasets.
• Input formats and batch processing: Accepts nucleotide sequence inputs in FASTA and GenBank formats and can process files from a directory.

Scientific Applications:

• Comparative genomics: Visualizes conserved and variable regions across bacterial genomes to compare genome structure.
• Microbial evolution: Reveals genomic rearrangements and conserved syntenic patterns relevant to evolutionary analyses of prokaryotes.
• Phylogenetics: Supports interpretation of evolutionary relationships by mapping conserved block patterns across strains or species.
• Genomic rearrangement and phenotype association: Aids identification of rearrangements potentially associated with phenotypic diversity, antibiotic resistance, or pathogenicity.

Methodology:

Implemented in Python to analyze input genome sequences, identify syntenic (colinear) regions, generate visualizations, and write intermediate files to a specified working directory.
