Main themes

Bioinformatics refers to a set of concepts and tools that are required for the analysis of biological data and the interpretation of the results. After a review of molecular biology basics and recent technologies for genome analysis, the course focuses on molecular biology databases (DNA and protein sequences), sequence comparison algorithms, identification of protein structural features (motifs), Hidden Markov models, selection of transcriptional markers, inference of transcriptional regulatory networks, and prediction of evolutionary relationship.

Aims

Regarding the learning outcomes of the programme of "Master in Biomedical Engineering", this course contributes to the development and the acquisition of the following learning outcomes :

AA1.1, AA1.2, AA1.3, - AA2.2, AA2.4, - AA4.3, -AA5.3

 

b. At the end of this course, students will be able:

 - to master the basic concepts of molecular biology for appropriate use of  bioinformatics tools,

- to design and develop tools or methods for  database management, information extraction  and data mining,

- to formulate informed decisions between the many  computational methods that are available for solving biological questions,

- to carry out a collaborative project aiming at the resolution of a bioinformatics problem and  taking benefit from complementary student's education and expertise,

- to use the information available in major sequence databases (Genbank, Uniprot) with a critical mind and with discernment,

- to master a software environment (EMBOSS, R, Bioconductor).

Evaluation methods

The first part of the written examination, in a closed-book format, focuses on algorithmic and statistical aspects, and accounts for 50% of the global note. The second part, in an open-book format, proposes a sequence to be analysed using the computer programs discussed in the classroom, and accounts for another 30%. The mini-projects account for 20% of the final evaluation marks. Students who failed the examination are not allowed to retake the miniprojects.

Teaching methods

The theoretical part consists of ex cathedra lectures in a classroom (30h).  The training sessions (30h) consist of a set of problems to be solved (mini-projects) and tutorials. The mini-projects are based on the algorithms discussed in the lectures. Teams of up to two students work on statistical and algorithmic aspects to solve biological problems, using a programming language of their choice (typically among R, Matlab, Python, or Perl). The tutorials introduce students to the methodology followed for protein function prediction, using the EMBOSS open software suite. The importance of the choice of the method and the analysis parameters is illustrated for common biological cases.
