You can use blastdb_aliastool to make a database alias for all those dbs, then blast against that alias. So if you had nt and refseq_genomic in that folder, you'd cd into /blast_db and do
ThenCode:blastdb_aliastool -dblist "nt refseq_genomic" -dbtype nucl -out combined_db -title "Combined nt and refseq_genomic"
Code:blastn -db combined_db -query contigs.fa -out out.blast

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...10-30-2026, 06:46 AM
