Reduced redundancy. Faster searches. More diverse proteins and organisms in your BLAST results. Check out our new ClusteredNR database – derived from the default BLAST protein nr database by clustering sequences at 90% identity / 90% length (details below).  Get quicker results and access to information about the distribution of your hits across a wider range of organisms and evolutionary distances.

Searching ClusteredNR

You can choose the ClusteredNR database in the Choose Search Set section of the BLAST submission form where you normally pick the BLAST database.  Simply select the Experimental databases radio button.  You can also select the checkbox to search both ClusteredNR and the standard nr at the same time allowing you to compare results (Figure 1).

Figure 1. The ‘Choose Search Set’ section of the BLAST submission form. Selecting the Experimental databases radio button chooses ClusteredNR. You can also perform simultaneous searches against the clustered and the standard nr by checking ‘Select to compare standard and experimental database.’ Continue reading “New ClusteredNR database: faster searches and more informative BLAST results” →
