Month 2025-01 — MicrobiomeData NMDC Automation (microbiomedata/nmdc_automation) Key accomplishments focused on delivering end-to-end data processing reliability, expanding project modeling, and stabilizing batch workflows that feed downstream sharing and validation pipelines. Key features delivered: - Globus Manifest and Batch Workflow Enhancements: Implemented retrieval of Globus manifests for all request IDs within a project, added a Globus class, and integrated manifest handling into batch file creation. Refined config/logging, updated manifest acquisition calls, and adjusted discovery logic (including biosample_ids retrieval via proposal_id). These changes improve data readiness and traceability for batch processing. - SequencingProject model integration and related config/CLI changes: Introduced SequencingProject model to track project-level metadata, renamed fields for study IDs, updated configuration and CLI behavior, and added utilities to insert and manage projects in MongoDB. - Get and insert project utilities: Added get_request() for project retrieval and insert_new_project_into_mongodb() to manage project persistence, with verify_downloads to ensure downloaded data matches GOLD expectations. - Documentation and code clarity: Enhanced comments, updated README usage notes, and added mapping TSV module for NMDC automation to support downstream data mapping tasks. Major bugs fixed: - MongoDB Query Robustness and Data Filtering: Fixed incorrect query keys, removed file_status from queries, improved data filtering for non-null request_ids, and refined sample exclusion logic to skip transferring or already transferred samples. Adjusted request_id type and related joins to ensure robust data retrieval. - Stability and cleanup: Implemented early exit in update_file_statuses when no samples have a request_id to prevent downstream errors; removed extraneous braces; filtered directories from file listings; fixed dictionary construction issues; improved join keys handling. - Misc configuration and env handling: Updated environment/config handling to align with new project modeling and CLI behavior. Overall impact and accomplishments: - Increased reliability and observability of end-to-end NMDC data processing, reducing manual intervention and operational risk. The batch workflow enhancements combined with robust MongoDB querying substantially improve data quality, traceability, and processing speed for sequencing projects. - Enabled scalable onboarding of new sequencing projects and more maintainable automation pipelines through clearer models, utilities, and documentation. Technologies and skills demonstrated: - Python (OO design, code refactoring), MongoDB querying and data filtering, logging and observability, CLI and environment configuration management, data export (CSV), and mapping TSV generation. - Versioned data handling and testable utilities for project retrieval and insertion, along with documentation updates for ongoing maintainability. Business value: - Faster, more reliable data processing and project tracking reduce time-to-insight for sequencing studies, enhance data integrity, and improve auditability across NMDC automation pipelines.
