[BioRuby] Problem with Bio::GFF::GFF2

[George Githinji]

Hi all,
I am try to parse a GFF file. The file looks like this

##gff-version 2
##source-version bepipred-1.0b
##date 2009-06-09
##Type Protein seq1
# seqname            source        feature      start   end   score  N/A   ?
#
---------------------------------------------------------------------------
seq1   bepipred-1.0b epitope          1     1   0.173  . .   .
seq1   bepipred-1.0b epitope          2     2  -0.043  . .   .
seq1  bepipred-1.0b epitope          3     3  -0.014  . .   .
seq1   bepipred-1.0b epitope          4     4   0.144  . .   .
seq1   bepipred-1.0b epitope          5     5   0.250  . .   .
seq1   bepipred-1.0b epitope          6     6   0.218  . .   .

....truncated

and i have written the following lines with an aim of extracting the start,
end and score attributes. but before that i wanted to know whether the full
attributes are available. so i did the following.

require 'rubygems'
require 'bio'
bep_gff = Bio::GFF::GFF2.new(File.open('/home/george/bpred.gff'))

 bep_gff.records.each do |record|
    puts record.attributes_to_hash.inspect
end

However, i get empty hashes.
Any ideas?

Thank you
