Mar 1, 2025March 2025 monthly summary for SPAAM-community/AncientMetagenomeDir: Delivered dataset expansion for host-associated libraries and implemented robust data quality fixes to improve data integrity and downstream usability. Added multiple new entries (Patrono2022, AVL001, Plasmodium malariae) to ancientsinglegenome-hostassociated_libraries.tsv, broadening taxonomic and experimental coverage. When a GitHub workflow issue prevented automated library ingestion, manual additions were performed to ensure dataset completeness. Implemented data quality and formatting fixes across host-associated libraries and sample data (separator fix, duplicate removal, library-treatment corrections, and geographic location standardization). These changes advance data reliability for meta-analyses and cross-study comparisons and demonstrate strong data curation and Git-based collaboration.
