The Zv6 zebrafish sequence data were produced by the Zebrafish Sequencing Group at the Sanger Institute and can be obtained directly from ftp://ftp.ensembl.org/pub/assembly/zebrafish/Zv6release/. All sequence data are made available before scientific publication with the understanding that the groups involved in generating the data intend to publish the initial large-scale analyses of the dataset. This will include a summary detailing the data that have beeen generated and key features of the genome identified from genomic assembly and clone mapping/sequencing. Any redistribution of the data should carry this notice.
