The NCBI Trace Archive is a permanent repository of DNA sequence chromatograms (traces), base calls, and quality estimates for single-pass reads from various large-scale sequencing projects. The Trace Archive serves as the repository of sequencing data from gel/capillary platforms such as Applied Biosystems ABI 3730®. The Sequence Read Archive (SRA) stores sequencing data from the next generation of sequencing platforms including Roche 454 GS System®, Illumina Genome Analyzer®, Applied Biosystems SOLiD® System, Helicos Heliscope®, and others. The Trace Assembly Archive stores pairwise alignment and multiple alignment of sequencing reads, linking basic trace data with finished genomic sequence.
