Now that's what I call user-friendly.

  Hello everyone,
  thank you, I found what I needed. You have to add                           

  -strand_arrow => 1

  in $panel->add_track, and 

  -strand        => +/-1,

  in $feature = Bio::SeqFeature::Generic->new options.

  Thanks
  Emanuele

    Emos- Without the code, I can only guess, but you might not be providing
    the options correctly. Have a look at
    http://www.bioperl.org/wiki/Drawing_with_multiple_glyphs_in_a_single_track
    for something that may help.

      Hello,
      I've tried all the arrows suggested in
      http://search.cpan.org/~lds/Bio-Graphics-1.982/lib/Bio/Graphics/Glyph/arrow.pm,
      but I can't figure out how to tell in the options of $panel->add_track the
      strand of the feature I'm adding.
      I'm drawing DNA elements from a local DB, and I have a field "strand" which
      can be + or -.
      Please help!
      Emanuele
