Jan 1, 2025ProteoWizard/pwiz - 2025-01 monthly summary Key features delivered: - User Interface Enhancements: Hide internal properties from property sheets in derived forms (ViewMenu, EditMenu) using Browsable(false) and DesignerSerializationVisibility on SkylineControl properties. Added new columns to the Document Grid for LCPeakIonMetricsMS1 and LCPeakIonMetricsFragment to surface injection time and ion current metrics at the apex and across the LC Peak. - Remove bootstrap LOQ calculation feature: Removed UI and backend logic for bootstrap-based limit of quantification calculation, reducing maintenance surface and simplifying user workflows. Major bugs fixed: - File processing and spectrum library handling improvements: Fix invalid score type handling for EncyclopeDIA-generated .blib files and allow .ssl spectrum library files to reference data in subdirectories. - MS data processing fixes: Correct handling of ambiguous spectra in MSFReader (remove ignore-ambiguous-matches code) and fix Peptide ID Times > Matching data alignment across all replicates. - Build/test infrastructure reliability: Ensure correct build order (tiny-msf before tiny-msf-keep) to reduce intermittent test failures. Overall impact and accomplishments: - Enhanced data quality and reliability across the proteomics pipeline, with more robust file parsing, accurate MS data interpretation, and predictable test outcomes. - Improved user experience and faster workflow through UI refinements and the removal of an unused LOQ calculation path. - Reduced maintenance burden by stabilizing build/test pipelines and removing obsolete features. Technologies/skills demonstrated: - C#/WPF UI development (descriptor attributes: Browsable, DesignerSerializationVisibility) and data-grid enhancements. - File I/O and spectrum library handling, MS data processing logic, and ambiguous-spectrum handling corrections. - Build/test pipeline stabilization and maintenance of data processing integrity.
