BRIG v1.1.1

Highlights

  • Multithreaded BLAST (#42) — adds -num_threads to all BLAST calls; defaults to all available CPUs; configurable via --threads <n> CLI option or blastThreads XML profile attribute
  • Fix same-filename collision (#53) — BLAST output .tab files are now prefixed with ring/sequence indices (r{ring}s{seq}_) so files with the same name in different directories never overwrite each other
  • Configurable GC skew/content window (#56) — new --gc-window <n> CLI option and gcWindow XML attribute let users set the window size for GC calculations; falls back to auto-scaling when not set
  • Auto-release workflow — merging a PR labelled release into master automatically bumps the patch version, creates a tag, and triggers the existing release pipeline to build DMG/MSI/JAR packages

Other changes

  • Bump actions/upload-artifact to v7, actions/download-artifact to v8
  • Bump maven-shade-plugin from 3.6.1 to 3.6.2
  • CI now installs BLAST+ via pixi and runs E2E tests
  • Added pixi.toml for reproducible BLAST+ dependency management

What is BRIG?

BRIG generates circular comparison images of multiple genomes using BLAST. It visualises sequence similarity, GC content, read coverage, and custom annotations as concentric rings around a reference genome.
