makeudb_usearch command


The makeudb_usearch command creates a UDB database file from sequences in a FASTA file. Index parameters are set to defaults for usearch_global and usearch_local. These defaults can be overridden by specifying index parameters on the command line.

The name of the UDB file is specified by the -output option.
