Aug 1, 2025During August 2025, the ProteinPaint project delivered a set of high-impact features, reliability improvements, and maintainability enhancements. Key functional work included SSGSEA support with a new data type, and a UI that dynamically adapts labeling and improves geneVariant layout. In addition, app deployment was streamlined by consolidating GDC launchers and making ClinVar termdb optional. On the data pipeline, Rust-driven loading and validation pathways were strengthened, error handling was expanded, and testing/documentation coverage increased. These efforts deliver faster data loading, fewer user issues, and a more scalable foundation for additional data types and analyses.

Jul 1, 2025July 2025 delivered focused feature enhancements and stability improvements for stjude/proteinpaint, advancing data accuracy, visualization capabilities, and maintainability. Key features included enabling Grin2 plot type when single-sample-mut queries are available, extending the run route to generate a list of required chromosomes for both Rust and Python inputs, and broadening data visualization with GDC support and runtime filtering. The month also added multiple new chart types (summarizeMutationDiagnosis, summarizeCnvGeneexp, summarizeGeneexpSurvival, summarizeMutationSurvival) and delivered UI refinements to improve user experience. In addition, a comprehensive maintenance sweep reduced noise, hardened error handling, and cleaned up code paths to support faster future iterations. Overall, these changes improve business value by enabling deeper, faster insights from clinical data and reducing time-to-insight for researchers and analysts.

Dec 1, 2024December 2024 performance summary for stjude/proteinpaint: Delivered substantial features to visualization and data exploration, while strengthening quality and maintainability. Key features delivered include MassNav enhancements with activeItems support, color handling improvements, notes, and CNV-related prototype/height logic; MassNav was made optional to reduce UI clutter. Implemented a robust GDC MAF UI feature: table sorting enabled and finalized, improving data discovery and usability. Groundwork for data modeling enhancements included a Phenotree column for additional attributes (WIP) and multivalue TV OR joining. Major testing and reliability improvements were achieved with added unit tests for new/updated features and a major test infrastructure refresh (TermDB test rebuild). UI/UX and stability fixes covered Scrna gene expression violin UX and CNV legend entries, CSS/layout improvements, and table header style customization; cleanup included removal of unnecessary logs and unused lines and a TypeScript compile error fix.
