The original version of the article ‘Gigwa-Genotype investigator for genome-wide analyses. GigaScience 2016 5:25’  unfortunately contained an error.
In the Technical insights - Data structure section, the mentioned WIDDE application actually refers to “WIDDE: a Web-Interfaced next generation database for genetic diversity exploration, with a first application in cattle. BMC Genomics 2015 16:940” , not to “Knowledge engineering tools for reasoning with scientific observations and interpretations: a neural connectivity use case. BMC Bioinf. 2011;12(1):351”.
