Dear BioCs, I need to download a complete set of experiments from GEO, with some hundred of single experiments. To import directly in R I want to use AnnBuilder, but I can only download one array per time. How can I download them in batch mode throught AnnBuilder? Thanks in advance Claudio Isella.

Claudio, You may want to look at using the GEOquery package. If you have a GSE or GDS accession, GEOquery will download all the associated information and make R objects out of it. The associated vignette shows how to convert these objects to exprSets or limma MALists. Sean
