The result of "$taxidmapping" is: BL_ORD_ID:0 0 and etc.

[maruiqi0710]

I donwload nt from ftp.ncbi.nlm.nih.gov:/blast/db/FASTA/nt.gz.
Then, make db using:

makeblastdb -in ./nt -dbtype nucl -out ./nt_blast_db

Then, run

"$blastdbcmd" -db "$db" -entry all -outfmt "%a %T" > "$taxidmapping"

The result of "$taxidmapping" is:

BL_ORD_ID:0 0
BL_ORD_ID:1 0
BL_ORD_ID:2 0
BL_ORD_ID:3 0
………………

What's wrong?
