From: An analysis of the Sargasso Sea resource and the consequences for database composition
Distribution of BLAST e-values. Here the sequences all come from BLAST searches of the Combined-nr database. Here BLAST runs with the 237 target sequences finds as many related Sargasso Sea sequences as sequences from the current database. The distribution of the sequences is a difference between the two sequence resources though, sequences from the Sargasso Sea databases are found with higher E-values on the whole, something that is probably a side effect of the high proportion of fragments in the resource.
