I extracted a subset of sequences from the nt database and I want to make a blast database with those sequences including the taxon id's.
If I execute the following command :
./ncbi-blast-2.6.0+/bin/makeblastdb -in ntselection.fa -dbtype nucl -taxid_map nucl_gb.accession2taxid -parse_seqids
I get no errors and the database is working with blast, but with output parameter
-outfmt '6 qseqid sseqid stitle sgi sacc pident length qlen evalue bitscore staxids' there are no taxon id's in the output.
What is the correct command and input files? If I use the gi_taxid_nucl.dmp I also get no errors but no blast database is made.
