Local BLAST databases

Databases can be made available for BLAST searches in several ways:

For BLAST searches against a small amount of sequence data, a sequence list can be specified instead of a database when launching the BLAST tool (see BLAST against local data). A database for those sequences will be created as part of that job. This adds to the overall execution time, so if those sequences will be used for multiple searches, creating a BLAST database and referring to that when launching searches is likely to be preferable.
