QTLFinder is a plugin for xQTL that enables users to quickly search and plot genomic data. It is most prominent as the home page of www.wormqtl.org. Feedback from Yang that needs doing: As a user, I want to be able to select a dataset to search in from the dropdown box as a filter. As a user, I want to download the data used to create my plots. As a user, I want to download my currently shopped phenotype records in a CSV. As a user, I want to be able to calculate the correlations between all shopped phenotypes. As a user, I want to know how to best search my favourite gene. What ID or nomenclature will give the best hits? As a user, I want to have a better cis-trans plot with names indicating which traits have high LOD scores.
