There are already five databases in WebQTL. Each will eventually have a page like this describing the data source and appropriate citations to these databases. The great majority of data in WebQTL were generated in our own labs and those of our collaborators.  We welcome you to use these data, but caution you that there are inevitably lots of little problems and issues that may compromise some results. Be cautious and skeptical. Ask us questions before you leap to publication. And please, if you find the data useful or can verify or refute data, LET US KNOW. We would like to add you to our reference section and add links to improvements.
