Algorithms in Bioinformatics - #27625
Information for participants
GENERAL SCHEDULE
Lectures will be in the morning from 9.00 - 12.00, and exercises in the afternoon from 13.00 - 17.00.
The morning sessions will consist of lectures and small
practical exercises introducing the different algorithms, and the afternoon sessions
will consist of programming exercises where
the algorithms will be implemented.
The main programming language will be C, and all program templates provided in the course will be written in C.
Prior knowlegde of C programming is NOT required. However, basic programming skills are required to follow the course.
LITERATURE:
The course curriculum consists of review paper and selected chapters from Immunological Bioinformatics,
Lund et al., MIT Press, 2005. All course material will be made available online during the course. All course
material is available here Course material.
