Sequences alignment and phylogeny

Sequences alignment and phylogeny (16/08/2016)

This training session is organized by the bios4Biol CATI and the Genotoul bioinfo platform and aims at initiating participants to molecular phylogenetics studies. You will discover how to build a sequence dataset, to align sequences, to edit and refine the resulting alignment.



This training is focused on the practice. It consists of 4 modules with a large variety of exercises:

  • Introduction (09:00 am to 12:30 am): history of phylogeny. Aims and interest of phylogeny.
  • Dataset construction (09:00 am to 12:30 am): homology definition. RBH definition.
  • Alignment by pair (09:00 am to 12:30 am): dotplot. Substitution matrix. Score definition. Alignment methods.
  • Multiple alignment (14:00 pm to 17:00 pm): alignment methods. Editing.


The session will take place in the room ‘salle de formation’ at INRA center of Toulouse-Auzeville.


Prerequisites: ability to use public sequences databank and basic softwares in bioinformatics. Training materials will be available on the website before the session. Slides in a “taking notes” format will be downloadable from our web site. A Unix reference command leaflet will also be provided. Only the latter will be available during the session.
