Create local BLAST databases

In the CLC Genomics Workbench you can create a local database that you can use for local BLAST searches. You can specify a location on your computer to save the BLAST database files to. The Workbench will list the BLAST databases found in these locations when you set up a BLAST against local data.

DNA, RNA, and protein sequences located in the Navigation Area can be used to create BLAST databases from. Any given BLAST database can only include one molecule type. If you wish to use a pre-formatted BLAST database instead, see Add pre-formatted BLAST databases.

To create a BLAST database, go to:

        Toolbox | BLAST (Image blastsearch)| Create BLAST Database (Image create_blast_database)

This opens the dialog seen in figure 11.15.

Select sequences or sequence lists you wish to include in your database and click Next.

In the next dialog, shown in figure 11.16, you provide the following information:

Click Finish to create the BLAST database. Once the process is complete, the new database will be available in the Manage BLAST databases dialog, and when running BLAST against local data.
