The Trace Archives includes the following archives:
- The Sequence Read Archive (SRA) stores raw sequence data from "next-generation" sequencing technologies including 454, IonTorrent, Illumina, SOLiD, Helicos and Complete Genomics. In addition to raw sequence data, SRA now stores alignment information in the form of read placements on a reference sequence.
- The Trace Archive serves as the repository of sequencing data from gel/capillary platforms such as Applied Biosystems ABI 3730®.
- The Trace Assembly Archive stores pairwise alignment and multiple alignment of sequencing reads, linking basic trace data with finished genomic sequence as found in GenBank.
