Hi, I have recently downloaded the dataset accompanying the 2002 article "A gene expression signature as a predictor of survival in breast cancer" by van De Vijver et al. published in the New England Journal of Medicine. There are a total of 24,496 spots on the array out of which 10,159 are contigs with unknown annotations, i.e. 41% of the total data are not annotated. The data set is now almost 4 years old. Have these contigs been annotated now, and if so where can I find information on them. Thanks in advance. Narinder S. Sahni

I have used this dataset for a practical. The attached script shows how I have annotated the data using data that translates the contig to accession numbers and batchgenefinder to retrieve EntrezGene ids and Locuslink. I hope the comments are clear enough to help you on your way.
