The first day of the summer school is a day of plenaries in the auditorium, introducing the themes of the 5 groups. The students have to choose one of the 5 thematic groups that they will follow for the following 6 days. In each group, the first part of the week will consist in theory and practical. The second part of the week the students will work in subgroups of 3-5 and carry on mini-projects on real data under the supervision of the trainers. The last day of the summer school is in the auditorium again and is a day of review and practice sessions for each mini-project.
