[Gmod-ajax] Representation of exons and introns with jbrowse

[Isabelle L. <isa...@ve...>]

Hello,

I am very interested in your tool jbrowse.

But I am not safe to use all its possibilities.

I have 2 questions:

1)  I want to show exon-intron strucutre of mRNA.

I ask the same question as Motokazu Ishikawa, but I did not find answer 
to his question under this site:

Under http: // mailarchive / forum.php sourceforge.net/? 
Forum_name=gmod-ajax
   [ Gmod-ajax ] Subfeature were not shown      Motokazu Ishikawa < 
m.ishikawa@is >      1      2009-10-16 00:44

Could I have the file GFF corresponding In the following tracks? 
(volvox.json)

    {
      "track": "CDS",
      "feature": ["CDS:predicted", "mRNA:exonerate"],
      "class": "cds",
      "phase": 1,
      "key": "Predicted genes",
      "category": "Genes"
    },
    {
      "track": "Transcript",
      "feature": ["mRNA:exonerate"],
      "description": 1,
      "class": "transcript",
      "subfeatures": true,
      "subfeature_classes": {
        "CDS": "transcript-CDS",
        "UTR": "transcript-UTR"
      },
      "arrowheadClass": "transcript-arrowhead",
      "key": "Exonerate predictions",
      "category": "Genes"
    },


Do sub-features well serve to display introns and exons for example, or 
otherwise to which are of use you they?

2) I have sometimes 100 in 200 elements for a track (ex ESTs)

How to decrease the height of these tracks?
Is it with the NClists?
Can you give me an example or give me the Web address where I can find it?

Best regards
