MalariaGEN aims to bring together malaria genetics with epidemiological information across both time and space. The project has two distinct but complementary goals to simplify genetic data reporting so that more users are able to analyse and interpret the key features of their data, focusing on what is of most importance for field research and malaria control in a timely manner and to create an open access global observatory across time and space for genetic variation and other relevant metadata such as malaria prevalence and deployment of control measures. This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/.
