Jun 1, 2026June 2026 — Delivered targeted platform, analysis, and collaboration upgrades for anvio (merenlab/anvio) that drive reliability, scalability, and scientific value. Infrastructure/CI/CD enhancements standardize environments and testing, enabling faster, safer deployments. KGML reaction network work enhances topology-aware analyses (partly cyclic chain detection and topology-based comparisons) with robustness improvements across checks. A new tRNA-seq Functional Affinity computation introduces a demand-weighted log-supply index, with CLI, docs, seed assignment fixes, and unit tests to improve reproducibility. Updated co-authorship metadata to reflect contributions. Targeted bug fixes to improve CLI stability and plotting edge cases, reducing crashes and improving user experience.

May 1, 2026May 2026 — merenlab/anvio: Delivered three core features delivering business value and technical robustness: (1) affinity analysis enhancements with standard errors on regression slopes, plus options for geometric mean-based affinity and explicit sample ordering, and isoacceptor processing cleanup; (2) charge-based metabolite matching in the reaction network to enable more precise mapping; (3) reaction chain robustness and efficiency improvements through subchain deduplication, precomputed chain information, and indexed candidates. Major fixes include code quality improvements (ruff --fix), removal of unreachable exception handling, and ensuring non-decoding anticodons are ignored. Overall impact: more accurate analytical results, faster and more reliable network mapping, and a maintainable codebase. Technologies demonstrated: Python, static analysis, data-structure optimization, and algorithmic enhancements in chain matching.

Oct 1, 2025In 2025-10, delivered two primary outcomes for merenlab/anvio: (1) KGML Walker Documentation Improvements with consolidated docs and clarified parameter behaviors, traversal rules, and edge cases (compounds chains, gaps, cycles, nonenzymatic reactions, termini), accompanied by docstring edits and artifact updates; (2) Codebase cleanup removing obsolete sandbox script 'anvi-script-predict-metabolic-interactions' to reduce churn and unused artifacts. These changes improve usability, reduce onboarding time, and lower maintenance overhead.
