Phylogeny inference and data analysis, spring 2011
Time schedule, prerequisites, content
Basic probabilistics and statistical inference are assumed as prerequisites.
The course is tailored for Bioinformatics Master program (MBI) and thus some knowledge on sequence analysis, working with sequence databases, sequence alignment, distance matrix based phylogenies by MEGA-software, are assumed to be known.
The course is, however, open for all students: additional sessions will be arranged for students who are not familiar with these basics (introduced in other MBI-courses).
Tuesdays 15-17 and Thursdays 14-16 in B120 and in computer class C128.
Time schedule for extra sessions (for non-MBI -students) in computer class during three first course weeks in negotiable (for example before or after lecture times).
The aim of the course is to elucidate both biological and statistical aspects of phylogenies, i.e. evolutionary trees and networks, which are elementary structures of differences among biological entities (species, individuals, genes, sequences in general), amenable to statistical inference. The major categories of phylogeny inference methods are distance matrix, parsimony, maximum likelihood, Bayesian and network approaches.
Exam (40 points) and homework assignments (20points): 4cr, essay (statistically or biologically focused): 2cr.
50-60 points: grade 5, 30 points: grade 1.
Course is focused on practical working => exam in computer class.
Week 1 program is for non-MBI (Bioinformatics Master program) students. Lectures and practicals in computer class overlap with topics which have in been in Introduction to bioinformatics / Molecules for bioinformatics: Basic phylogeny concepts, basic practical computer working and getting familiar with molecular sequence databases.

Tue 22.02, 15-17, C128, Results from datasets 1 and 2 + lectures on methods (2h session probabaly not enough, we continue until everything is done.)
Thu 24.02, 14-16, B120, Results from dataset 4 + lectures on networks and phylogeny examples (phylodynamics, phylogeography, phylogenomics, phyloprofiling).
Thu 03.03, 16-20, C128, EXAM.
Working in 2-4 student groups. You get 20 points for the total 60 points (40 from exam) by doing these. Note that the course is focused on practicals and you need these skills in exam (reasonable aspects, not sophisticated details).
IV period: Practical project work in computer class and at home, time schedule negotiable (4-6 cr), topics to negotiated at the end of part I
The project is based on sequence data collected from databases.
This is registration to part I. At the end of III-period you should decide if you continue to part II.
Did you forget to register? What to do.
