The 2003 Affymetrix GeneChip Microarray
Low-Level Workshop

The Alumni House, UC Berkeley Campus
Berkeley, California USA

August 7- 8, 2003

Registration is now closed!

See below for event details:

Affymetrix GeneChip microarrays have become a crucial component of gene expression and genotype research for many laboratories. Data analysis remains a major challenge for the effective use of GeneChip data. While many software tools and services exist to simplify data access, management, and analysis of microarray data, the availability of large numbers of microarray experiments and of reference data sets has motivated considerable interest in the research community to improve upon existing analysis methods.

Affymetrix would like to invite researchers engaged in algorithm development to a poster session in the evening of August 7 and a one day workshop on August 8th, 2003 in Berkeley, California to discuss low-level analysis issues related to GeneChip microarray data including; image analysis, DNA probe hybridization, normalization, quality metrics and summarization of probe-level data. We are soliciting proposals for talks and invite all non-speaking attendees to present posters. The goal of this meeting is to provide a forum for the open sharing of ideas and promote further research in GeneChip microarray analysis. Limited travel support is available.
