The impact of the papers we publish depends increasingly on the data they describe. In insisting on data access for referees and readers, we prioritize scientific integrity above all and place the interests of research participants before impact.
The Nature research journals insist that materials, methods and data be made available and that authors detail any conditions for access where these exist. In our shared guide to authors (http://www.nature.com/authors/policies/availability.html), we state:
The preferred way to share large data sets is via public repositories. Some of these repositories offer authors the option to host data associated with a manuscript confidentially, and provide anonymous access to peer-reviewers before public release.
It is the practice of this journal to check all manuscripts for appropriate data access prior to peer review and, where necessary, to contact the authors to ensure that essential data for transcript expression (microarray and RNA sequencing), exome sequencing (Nat. Genet. 43, 921, 2011) and genome sequencing are available to the referees. Deposition of microarray genotyping data sets is strongly encouraged where consent conditions permit. We also check with the authors that an active accession code for the data is available at the time that they receive the proofs of their accepted manuscript.
