Celebrating 20 years of Animal QTLdb

(Aug 25, 2024): A sum of 11,682 new QTL/associations have been curated into the database. (New additions less obsolete/retracted ones: Catfish: 0; Cattle: 1,066; Chicken: 3,021; Goat: 644; Horse: 0; Pig: 6,813; Sheep: 138; Rainbow trout: 0 -- Net increase: 11,682). To date, the current total number of QTL in the database: 277,842 [Breakdown by species -- Cattle: 192,247 (on 552 traits); Chicken: 18,602 (on 244 traits); Goat: 2,145 (on 81 traits); Horse: 2,216 (on 60 traits); Pig: 55,688 (on 407 traits); Sheep: 4,743 (on 167 traits); Rainbow trout: 2,201 (on 35 traits)].
( This is a joint release with the 22nd CorrDB release.)

In addition, as part of our data quality assurance efforts, updates works were performed on 2,020 SNP associations and 115 base traits data.

Database developments notes:
(1) Multiple Genome Support: Local SNP maps are updated with new EVA dbSNP release 6 (https://ftp.ebi.ac.uk/pub/databases/eva/rs_releases/) for 19 genome assemblies. In addition, SNPs are lifted to 3 more genomes for cattle (ARS_UCD2), pig (MARC1), and sheep (Rambo1) using our in-house procedures. This facilitated QTL/association data support for 22 genome assemblies. We will consider depositing this in-house tool for free download if there is a community need. (2) Towards data curation automations: Thanks to Yuepei Li and Kang Zhou from Qi Li's group in computer science at the Iowa State University for their excellent collaborative works, an AI powered literature classification tool has been implemented in the QTLdb the data curation pipeline which has greatly accelerated the literature data processing. (3) FAQ: the "Frequently asked questions" list has been updated with a few newly added items. The most recent one is on the "QTL sizes" in downloaded data. Please check it out for more details.
