EMBARGO/FAIR USE OF EPIGENETICS DATA: We are delighted to release unpublished epigenetics tracks to the community. We encourage others to use these data, but in doing so we also expect that they will respect our right to first presentation (including journal publications, pre-prints such as in bioRxiv, public conference talks, and press releases) of a genome-wide analysis of these tracks. This includes the use of genome-wide epigenetics data for generalized descriptions of gene-regulatory patterns in axolotl and evolutionary/developmental/regeneration analyses, on behalf of ourselves as data producers and collaborators. Therefore, please respect the embargo on the presentation of analyses using pre-publication data that we release via this website and relevant archives. Similar fair use statements apply to many genome assemblies such as those released by the Sanger Institute and the VGP.

Exceptions to the policy are for analyses of either a single locus, or a single gene family, or for use as a reference for mapping reads from independent studies. Individual tracks and datasets will be considered released from this embargo when they are expressly published, and the relevant reference(s) will be added to this website at that time. For any queries about using the data, referencing/publishing analyses based on pre-publication data or interest in contributing to genome-scale analyses please contact This email address is being protected from spambots. You need JavaScript enabled to view it..  We are also happy to make tracks from other groups available under this same fair use policy.
