Database developments:
Recent new database developments have been highlighted in our recent paper published in the 2022 Database Issue of Nucleic Acids Research, "Bringing the Animal QTLdb and CorrDB into the future: meeting new challenges and providing updated services", that include (1) A standardized protocol for adding new species to QTLdb/CorrDB; (2) Livestock SNP ID/name matching repository to assist SNP-based data curation; (3) A pipeline for mapping QTL/association data to a genome build, enabling support of QTLdb for multiple assemblies within a species; and (4) Extensive web portal revisions and web interface redevelopment in order to accommodate new tools while facilitate a straight forward user experiences using the web portal.
