Local BLAST databases
Databases can be made available for BLAST searches in several ways:
- Download pre-formatted BLAST databases from the NCBI using Download BLAST Databases (see Download NCBI pre-formatted BLAST databases).
- Specify locations where BLAST databases are stored at your site using Manage Blast Databases (see Manage BLAST databases).
- Use Create BLAST Database to create databases using sequences or sequence lists selected from the Workbench Navigation Area (see Create local BLAST databases).
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.
