I was trying to do some remote blast. Here is my command:
blastn -query myquery.fasta -db nt -out myblast.out -remote -num_alignments 10
-outfmt "6 qacc saccver pident sscinames length mismatch gapopen evalue bitscore"
I wanted to get the scientific name instead of taxid so I requested sscinames in my output format. I am almost certain that this worked for me a few months ago (according to my work log). Today it stopped working, returning N/A for the sscinames column with warning,
Warning: [blastn] Taxonomy name lookup from taxid requires installation of taxdb database with ftp://ftp.ncbi.nlm.nih.gov/blast/db/taxdb.tar.gz
for each query.
I would assume installing taxdb on my local computer wouldn't help.
I am using blast 2.6.0+
Any help is appreciated.
