Hybridization/DATA 1 Workshop

Data1 Presenters: A. Malcolm Campbell, Laurie Heyer, and Johanna Hardin; Hybridization presenters: Laura L. Mays Hoopes, Anne Rosenwald, Todd Eckdahl, Mark Salata, Mary Lee Ledbetter


Welcome to the GCAT workshop on Microarray Data Analysis, section 1 along with Hybridization laboratory experience.  In this workshop, you will learn some ways to teach and learn about microarrays and you will try out techniques for acquiring data, clustering data, and determining statistical significance of differences; then you will prepare labeled cDNA, hybridize it with microarrays, scan the slides, and analyze your own data. 


You may check into Copley Hall dorm (see maps on the Georgetown University web site) any time after 4PM on Monday, July 5. 

We hope you have configured any laptop computer that you want to use in advance (for directions, please see "computers" on the main web page for the workshop) but we recognize that not everyone has had time to do that.  If you did not bring a computer, do not worry; a number of computers preloaded with the software will be available for use during the workshop.


In most of the activities below, the hybridization workshop and the DATA1 workshop will work together; items in bold for Tuesday afternoon and Wednesday are times when Hybridization has a separate planning or activity meeting in a different location.
