Ph.D.-course:

Statistical analysis of gene expression data with R and Bioconductor
August 17 - 21, 2009

With follow-up workshop August 24 and 25:
Gene expression based on sequencing technologies


Time and Place

The course takes place from Monday, August 17 to Friday, August 21, 2009.

The lectures and exercises will take place at the

University of Copenhagen
Copenhagen Biocenter
Ole Maaløes Vej 5
DK-2200 Copenhagen Ø
Room(s) 4-0-24 (4-0-5)
The course is organized with a mix of lectures and supervised computer exercise sessions each day.

Course Description

The course aims to give Ph.D.-students in statistics as well as other Ph.D.-students a good introduction to data analysis of gene expression experiments using R and Bioconductor. The primary lectures/teachers of this course are international researchers on gene expression data analysis and/or developers of R-packages.
The course will be taught by the following: The list of topics that will be covered looks as follows:

All participants will receive a certificate of participation.

ECTS-credits: 5

Prerequisites

We will use R 2.9.1 and have provided an installation guide to ease the installation.

The participants are expected to have prior experience with R and statistics in general, and an interest in the biological questions. To be more specific, you are required to know how to use R for standard statistical analyzes such as doing a t-test or a linear regression, and you should know about the fundamental data structures such as vectors, lists and data frames. The participants are also expected to bring their own laptop for the exercises. We require that all participants prior to the course install the latest version of R and the latest version of Bioconductor (which releases will be announced on this web page when settled). The precise details for the required installation of R and the installation of required additional packages will be provided.

Program

Program:

All days are 9.00-17.00, but it is possible that we will end a little earlier some of the days. Lunch is 12.30 - 13.30. Every day will include combinations of lectures and computer labs. Both lectures and exercises take place in room 4-0-24 (we also have room 4-0-5 available).

Registration and Payment

Registration has closed for now. There are more than 65 registered participants and with a total limit of 50 participants it has been decided to close the registration.

The number of participants is limited to a total of 50, and the places are given after a first come first serve principle according to the following quota:

Others 15

The registration fee is:

Ph.D.-students and other academia: DKK 1000,-
Non-academia*: DKK 4000,-

which, among other things, will cover lunch, coffee/tea and the hand-out material.

*Employees in BioSys member companies can register at the academia rate of DKK 1000, cf. the BioSys member list. However, the total number of these BioSys discounts is limited to 15 and allocated on a first come first serve basis.
