BLASTn protein identity sequence

Question

[Rob]

Hi friends, I have this fasta file for bacteroides species and I did BLASTn for this vs other fasta file. How should I know what the name of species is? which header should I look in fasta file?

this is my fasta file:

result from BLASTn:

[lieven.sterck]

if you want some sort of taxonomic categorization, you might consider tools like KRAKEN and such (in stead of plain blast, though that should also work)

if you request tabular output you can specify that it also prints a column/field with taxonomic info

Look at the command you gave. Whatever species you gave as query, that's the one in the qaccver column. Check out this BLAST resource , if you haven't already. The documentation is very clear and helpful.

Edit: Upon rereading your question, it looks like you want to know what organism your data comes from? If that's the case, you want to run normal BLAST, not against a specific subject.
