Is MEGAN5 command-line could do species annotation by using accession number?

Question

[fanglujing]

Hi, there. I want to use MEGAN5 command-line mode to do species annotation. I blasted my nucleic acid sequence against NR database, and get tab format output file. The second column of this output file is accession number rather than GI number. MEGAN5 could parse blast output which contain gi number. So, Is that possible to do species annotation by using blast output wich accession number? Thanks a lot.
