[BioRuby] Bio::Blast not fully functional?

[Fredrik Johansson]

Hello all,
I am reading in the tutorial at
http://dev.bioruby.org/wiki/en/?Tutorial.rd
about BLAST and I try to use it according to this tutorial (see the code
below).
However, many of the entries in the 'hit' variable in the code below
seems to be nil. hit.identity and hit.target_seq are for example two
methods that just answer nil when I call them. Am I missing something?

#!/usr/bin/env ruby
require 'bio'
factory = Bio::Blast.remote('blastp', 'nr-aa')
Bio::FlatFile.open(Bio::FastaFormat, '/home/fred/pdb/test.fasta.txt') do
|ff|
  ff.each do |entry|
    report = factory.query(entry)
    report.each do |hit|
      if hit.evalue < 0.001
         puts hit.target_id
         puts hit.target_seq
      end
    end
  end
end

Thanks for any help!
Best regards,
Fredrik Johansson
