Animal Trait Correlation Database

The Animal CorrDB Releases

(Dec 27, 2012): The first public release of Animal Correlation Database (CorrDB) included 3,635 cattle correlation data (Genetic Correlation: 2,309; Phenotypic correlation: 2,057; Residual correlation: 95l Environment correlation: 9) on 238 cattle traits; and 519 heritability data on 272 cattle traits.

Functions: A co-development strategy has been taken to share tools and resources with the QTLdb. Modified data tables, scripts, and routines from QTLdb are serving the purposes well for PubMed references and trait ontology managements within and between the two databases. Development of data curation pipelines is consider the needs from each database, thus significantly saving time and efforts.

(Dec 21, 2017): A sum of 842 new correlations (Genetic correlation: 521; Phenotypic correlation: 303; Residual correlation: 18) and 113 heritability data on 64 cattle traits.
( This is a joint release with the 34th QTLdb release)

Database developments: (1) The development of the initial sets of curator tools has completed for the Animal Correlation Database (CorrDB). With this release, we open the CorrDB curation for free registration for anyone who wish to be a curator to enter own or public correlation and heritability data. (2) As part of the Animal QTLdb/CorrDB co-development efforts, functions are developed to link QTL data with trait correlation data through common trait terms where such data exist. For example, within the CorrDB, under the Table View of correlation data, a hyper-linked red "QTL" label is added when QTL data exists on the trait; Like-wise, within the QTLdb on the trait search results, an hyper-linked tag is added on traits where correlation data are found.

(Apr 29, 2018): A sum of 7,541 new correlations [Break down by species -- Cattle: 4,823 (on 161 traits); Chicken: 421 (on 42 traits); Pig: 1,217 (on 84 traits); Sheep: 1,080 (on 38 traits)] and a sum of 1,015 heritability data [Break down by species -- Cattle: 706 (on 188 traits); Chicken: 75 (on 43 traits); Pig: 177 (on 63 traits); Sheep: 57 (on 40 traits)] have been curated into the CorrDB.
( This is a joint release with the 35th QTLdb release)

Database developments: (1) Curator tools improvements and debugs continued. (2) Special Note In order to maintain a high standard for data integrity and for better quality controls, a total of 3,628 historic correlation data were taken offline and re-entered into the database with data integrity check mechanisms newly built into the curator tools.. Even with this reduction, the total number of data records still increased by 3,913 from the last release, representing a 87% net data increase in the database.

(Aug 23, 2018): A sum of 2,099 new correlations [Break down by species -- Pig: 188 (on 9 traits); Cattle: 1283 (on 71 traits); Chicken: 628 (on 40 traits); ] and a sum of 424 new heritability data [Break down by species -- Pig: 55 (on 23 traits; Cattle: 172 (on 95 traits; Chicken: 157 (on 67 traits; Sheep: 40 (on 38 traits; ] have been curated into the CorrDB.
This is a joint release with the 36th QTLdb release)

Database developments: (1) A Frequently Asked Questions section has been added to the CorrDB. This is to address common questions raised with regard to design, usage, application, utilities, new developments, and other related issues in the use and development of the CorrDB. (2) A set of data release tools has been created to assist with consistent, flawless data review and release processes for CorrDB. This included some essential data constringe checks and complex queries to gather data status statistics for release processes.

Database developments: (1) Goat CorrDB: Groundwork has been laid by preparing the goat trait management space and other required information in order to allow the curations of published heritability data into the databases. (2) New dbxref data link services were added to allow external URL links to specific correlation data across species. Such links are often used by web services, API tools, or database xref pointers. See FAQ for details. (3) Frequently asked questions updated with the additions of new items, updates to existing items, and corrections to several items.

Database developments: (1) Progress is being made to improve the web interface for better data summary, query, and data representation reports. The initial visible change is the new front page with new data summary tables. Further changes will include sub-page reformats to reflect multiple reports on the same pairs of traits, and/or correlation types (phenotypic, genetic, environmental, residual), and reports by species. These improvements are made possible by recent addition of a database routine to perform post-curation data processing for improved structural data queries. This is an on-going process; stay tuned for new updates. (2) Continued improvement of data curation tools by adding data summary for curators to be better informed when at certain part of the curation process, and by adding direct work flow links between tools. (3) The Animal CorrDB are published on Figshare open access platform through the Iowa State University Library. Subsequently, now each database has an universal Digital Object Identifier (DOI), and all are covered by the Creative Commons licenses. As a result, there can be alternative ways how the users of the QTLdb or CorrDB can properly cite the use of the database resources and/or tools. Please check each database website to find more details (click on respective web page footages for copyright claims, and citation details; the same information is pre-pended to all download data files as well).

Database developments: (1) Web portal on Animal CorrDB web site are extensively have been extensively reformed. A number of new data filters along side of search / browse functions provides additional helps by providing data scopes for users to have an idea what to expect rather then left to guess what to search for. Added links and flags on web pages can effectively enable users to traverse from one data scope to another (e.g., from traits to QTL/association data; from heritability data to correlation data; from a table view to graphic view. Linking traits to VT/LPT/CMO trait ontologies facilitates data links with external databases where such ontologies are used. (2) Added Data Summary text table on several pages to provide extended information on current data window. A featured function is a display of median, interquartile ranges of heritability data when multiple measurement results exist on the same trait.

( The next database release will be in late December, 2021 )
