   ==== [[faq-B10]]4. Can I search for associations across more than one trait at the same time?
   
  -True multiple trait searching is currently not possible. The search bar searches for the exact text match of the search term entered within a range of Catalog fields, along with any related traits through the mapped ontology fields. For now, we would recommend searching by a more general trait, e.g. "schizophrenia", then selecting any desired compound traits from the trait filter dropdown e.g. “Bipolar disorder and schizophrenia”, “Schizophrenia or bipolar disorder”. Alternatively the data download enables complex analysis. We are working to improve this feature of the search in the near future. You can view our prototype trait-based search page at  http://www.ebi.ac.uk/gwas/beta/efotraits, which allows easy visualization of all associations with a trait, or combinations of multiple traits.

   ==== [[faq-B11]]5. Why did my search return no results even though I am sure there used to be a trait like this in the Catalog?
   Our search functionality is currently unable to allow for typos or term variations, so if you accidentally type "beast cancer" instead of "breast cancer", you will not get any results. Equally, "metabolic disorder" won't return any results while "metabolic disease" will return loads. A browseable list of all reported traits is available link:http://www.ebi.ac.uk/gwas/search/traits[here] and autocomplete functionality for the search box is coming soon. In the mean time, if you get stuck, we recommend varying your search term or searching for your term in http://www.ebi.ac.uk/efo[EFO] to get an idea of what other terms might be available.
  
positive.code: ==== [[faq-B5]]5. How can I identify variants in linkage disequilibrium (LD) with a variant?
  
  LD calculation between a variant of interest and its surrounding variants can be accessed programmatically using the Ensembl REST API (http://rest.ensembl.org/documentation/info/ld_pairwise_get) where you can specify a variant ID, a window size of the region surrounding the variant, a population and a cut-off for the calculation results.
  In case of a dataset with more than 1 variant of interest, several independant calls to the Ensembl REST API (http://rest.ensembl.org/documentation/info/ld_pairwise_get) can be done. Variants in LD with a specific GWAS Catalog variant can also be visualised on our new prototype variant page http://www.ebi.ac.uk/gwas/beta/variants.

  ==== [[faq-H1]]1. Is there a way of programmatically retrieving data from the GWAS Catalog?
  
  The GWAS Catalog REST API is now available for beta testing at http://www.ebi.ac.uk/gwas/labs/rest/. Please note that as this is only a beta release, we do not guarantee the stability of the endpoints. We make every effort to group major changes into a single software release, which we communicate to users via our \gwas-announce@ebi.ac.uk mailing list. link:++mailto:gwas-announce-join@ebi.ac.uk?subject=subscribe&body=Please subscribe me to receive GWAS Catalog updates++[Subscribe here].
  
  
  ==== [[faq-H2]]2. How do I use the GWAS Catalog REST API?
