module Bio::SeqIO::staden::read

Currently, the tracefile formats (except for SCF) require installation of the external Staden "io_lib" package, as well as the Bio::SeqIO::staden::read package available from the bioperl-ext repository.

Voici ce que j'ai trouvé :
Ext package
how to use the Open Bioinformatics Foundation Subversion server

En suivant le lien de Bioperl-ext on obtient ceci ... est ce ce lien qu'il faut ajouter aux librairies? ou est-ce le module à télécharger?

En ajoutant ce lien à mes librairies, ppm s'est mis à jour mais aucun module nommé Bio::SeqIO::staden::read ou bioperl-ext


Comment puis-je installer "io_lib" package et Bio::SeqIO::staden::read?




Merci pour votre aide,
