Course Syllabus

Instructor: Istvan Albert

Course records: PSU ELion

Course registration: BMMB 597D - Bio Data Analysis

The purpose of this course is to introduce students to the various applications of high-throughput sequencing including: chip-Seq, RNA-Seq, SNP calling, metagenomics, de-novo assembly and others. The course material will concentrate on presenting complete data analysis scenarios for each of these domains of applications and will introduce students to a wide variety of existing tools and techniques. We expect that by the end of the course work students will:

Access to a Mac or Linux computer is necessary to perform the homework. Only Mac OSX (Tiger/Leopard) and Linux operating systems are supported.

Grading and Homework

All Penn State Policies regarding ethics and honorable behavior apply to this course.

The final grade will be an average of the grades obtained on homework and a project. Please refer to the information in the first lecture. Homework will be handed out during each lecture in the form of exercises that will need to be turned in at the beginning of each week.

We want to emphasize that the primary goal of this course work is to improve students ability to handle and interpret data sets. Therefore the evaluation process is relative to the initial aptitudes. We aim to focus on developing permanent skills and talents that are not just immediately useful but also provide the foundation for further more in depth understanding of informatics in general.
