October 30, 2003 (Press Release) --
during the years, the unorganized submission of sequencing reports to databases has led to significant data repetition that both slows down the speed and reduces the effectiveness of information retrieval. to solve these problems metalife team developed a new product called nr (non-redundant) bio explorer, where the similar sequences were identified by all-against-all FASTA search. the sequences having a similarity over a certain threshold were unified in a cluster, and depending on the level of relationship to the cluster's major sequence, they were designated as: fragments, identicals, isoforms, isoform fragments, matures, overlaps, similar and variations. in contrast to other databases that cluster either only sequences or both sequences and annotations but for a limited number of organisms, nr bio explorer clustering affects both sequences and annotations of all species included in metalife bio explorer, providing a wide non-redundant database with higher level of annotation.
in addition to the cluster-based analysis, a sequence orientated investigation is also possible, since each cluster member is hyperlinked to bio explorer, as well as metalife protein and genome viewers.
