The Ensembl trace repository provides a permanent archive for single-pass DNA sequencing reads and associated traces and quality values. These data come from whole-genome shotgun projects, EST projects, and other large-scale sequencing projects. Data is regularly exchanged with the NCBI trace archive.
Current services include the ability to examine individual reads by name, to search the whole archive or subsets of the archive with another DNA sequence using SSAHA (a fast sequence search) and to download sets of read sequences in fasta format and associated quality values by FTP.
Requests for large data sets of complete trace information to be sent by tape should be made to trace-request@ensembl.org
The trace repository currently contains 1,910,538,513 traces from 1513 species. [trace statistics]
Use the search boxes to retrieve a count of traces summarised by species (e.g. Mus musculus), trace sequencing centre (e.g. SC), or trace type (e.g. WGS). Search terms can contain wildcards (e.g. Mus.*).
In the week ending 02-Jul-09 504,035 traces from 74 species were added to the repository.
