| Parameter | -d |
|---|---|
| Function | Specifies the target database(s) |
| Default | nr |
| Input format | string |
| Example | To search database named est_human, use: -d est_human |
Note:
Use database file name WITHOUT the file extension. Even though multiple databases can be specified in command line, using -d "nr est", database alias file is a better way to call multiple databases. For more information on database aliases, see:

Search multiple large databases together may encounter memory related problems.
