2009: Second Bioinformatics Meeting of the Luxembourg Bioinformatics Network (LuciLinX)
The symposium took place on October 9th 2009 at the University of Luxembourg, Campus Limpertsberg, Science Building. The meeting was organised by the Systems Biology Unit of the Faculty of Life Sciences of the University of Luxembourg, in cooperation with all the LuciLinX member institutions.
The format of the 2009 edition was different from the previous year. The morning programme was dedicated to talks and presentations, while the afternoon featured 2 parallel sessions of practical workshops.
The symposium was again attended by around 100 participants. The workshops were highly successful, with all seats taken and some attendants even sitting on the floor.
Funding was provided the University of Luxembourg and CRP-Santé.

Session 2
Protein identification
By: Kjell Sergeant
Topics: After a brief introduction on the basic opportunities and problems associated with proteomics, the focus will be mainly on the application of the most frequently used software tool for database dependent protein identification. Using examples from own research as raw material, the use of this and other tools will be explored from identification of proteins isolated from fully characterized species, over the study of proteins from non-model species and the identification of simple post-translational modifications.
Basics of systems biology

Topics:- Introduction to (Bottom-Up) systems biology
- Overview of the theoretical topics covered in the Master in Integrated Systems Biology
- Some useful computational tools
- Hands on - case study: Analysis of a small transcriptional network using nonlinear dynamical modeling
