Hello, If I execute the following three lines: library('GEOquery') gds <- getGEO('GSE2034') eset <- GDS2eSet(gds) I get the following error message after the call to GDS2eSet(): Error in function (classes, fdef, mtable) : unable to find an inherited method for function "Table", for signature "GSE" I'm using R version 2.6.0 and GEOquery version 2.2.0 (see details below), but it also happens with R version 2.5.2 and GEOquery version 2.0.6. Any help would be appreciated. Thanks. -Ben ---------------------------------------------------------------------- ----- > eset <- GDS2eSet(gds) trying URL 'http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?targ=self&acc=GPL96&for m=text&vie w=full' Content type 'geo/text' length unknown opened URL .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... .......... ..........

NCBI GEO nomenclature can be tedious at times. A GSE record is not the same as a GDS record. GDS2eSet() will only work on GDS records, not GSE records. I have made some relatively recent changes to GEOquery to allow loading of GSEMatrix records from GEO. > gseSetList <- getGEO('GSE2034',GSEMatrix=TRUE) > names(gseSetList) [1] "GSE2034_series_matrix-1.txt.gz" "GSE2034_series_matrix-2.txt.gz" It turns out that the GSE is too big for MS Excel (NCBI GEO targeted these files for Excel!), so two files are needed. If you look at either member of the gseSetList, you will see that each is an ExpressionSet that you can simply combine. Hope that helps. Sean
