Taxonomy

{gi -> taxid}.(根绝文件的拓展名来识别)

Probably you should do the match in the bash first by using script"

 grep ">" nt-18S.fasta | cut -f2 -d'|' | sort | uniq >gi.txt
 tabtk_subset /biostack/database/taxonomy/gi_taxid_nucl.dmp gi.txt 1 0 >gi_match.txt 

Then using the generated gi_match.txt as the inputs for parameter dmp, this operation will save your time, no needs to load the entire database.
