BI201 Gene Expression Analysis
From Bioinformatics.Org Wiki
This course helps to demystify Affymetrix analysis so that any researcher can take the basic steps to go from a chip image to a list of genes that are up- or down-regulated in an experiment. Various tools will be covered, e.g. Affymetrix Expression Console (replacing GCOS), Microsoft Excel, MathWorks MATLAB, and free tools like R/Bioconductor and dChip. It is geared towards researchers who conduct microarray experiments to study genome-wide expression changes and understand the underlying mechanisms of gene regulation in samples of interest.
Most scientists are not able to analyze the resulting data themselves, and they are not able to get desired results using traditional tools like Microsoft Word and Excel or with advanced software provided by commercial vendors. The freeware solutions come either with a steep learning curve or as black-box interfaces that provide limited functionality with little or no technical support. In the midst of all this is the fundamental lack of understanding among scientists on how the technology works and what the fundamental parts of the analysis are.
No experience is required, although prior experience with any other programming language will be helpful. Math skills will also be useful.
- Session 1 & 2: Introduction to Expression Console – the environment, creating and saving experiments, importing and exporting data, normalization settings, from DAT->CEL->CHP->RPT files and their significance, importing and exporting data
- Session 3 & 4: dChip software: importing expression data and annotation information into dChip, normalization, gene filtering, clustering, visualization along chromosome, gene ranking by confidence intervals and pvalues for group studies, exporting to Excel.
- Session 5 & 6: R/Bioconductor: installing and configuring bioconductor for gene expression analysis, obtaining normalized gene expression scores, performing statistics to obtaining differentially regulated genes in time series or group studies.
- Session 7 & 8: MATLAB: importing expression data in MATLAB, thresholding, normalization, gene filtering, clustering, classification, statistical gene ranking for time series and group studies, exporting to excel, building custom user interfaces for advanced applications.

Live instruction held on-line
On-line/live courses use the WebEx on-line meeting system. Access information will be provided prior to the start of the course. Unless otherwise noted, each lecture begins at 16:00 GMT and runs for about two hours, depending on the topics covered.
For those who cannot attend the lectures at those times, the lectures will be recorded and placed on the course website as AVI video files each day, within one day. Students will also be able to communicate with the instructor and other students via the course forums. Lecture attendance is therefore not required.
Since this will be an interactive, hands-on workshop, all attendees will need a computer with a broadband Internet connection (1 Mbps or faster is strongly recommended for those watching the live lecture), a sound card with speakers, a modern Web browser, and Java. A microphone and webcam are not required but may be used.
This course is certified by the Bioinformatics Organization, Inc., the largest international affiliation in the field, and it will count as 6 "Continuing Scientific Education" (CSE) units (one unit per contact hour) within the Organization. Students completing the course will receive a certificate attesting to that.
For any course type, if a student is not satisfied with the conduct or content of a course, they may request a full refund within the first two days of lecture. After two days but within a week, a 50% refund will be granted. After one week, a 100% credit toward another course will be granted. No refunds or credits apply beyond those stated here.
