search_global command
Comprehensive database search. All database sequences are aligned to the query, no index is used. Alignments are global. Much slower than usearch_global for large datasets; mostly useful for ad hoc queries on small datasets. Sensitive to arbitrarily low identities.
An identity threshold must be specified using the - id option .
A database file must be specified using the -db option.
The - strand option is required for nucleotide databases.
Nucleotide, protein and translated searches are supported.
