Bit vector files are created by the udb2bitvec command. The recommended sequence database is the Greengenes 97% representative set. You should use the -wordlength 13 option of makeudb_usearch to create the udb file, as shown below.

usearch -makeudb_usearch gg97.fa -wordlength 13 -output gg97.udb

usearch -udb2bitvec gg97.udb -output gg97.bitvec
