HI Gaurav Have you solved your problem?. I am also facing the same problem. I did it as James mention,but still i m not able to get phenotypic information. Here is the steps:- gse <- getGEO(filename='GPL10265/GSE21111_family.soft.gz',GSEMatrix=TRUE) pData(gse[[1]]) OR phenoData(gse[[1]]) Error in pData(gse[[1]]) : error in evaluating the argument 'object' in selecting a method for function 'pData': Error in gse[[1]] : this S4 class is not subsettable Thanx On Thu, May 19, 2011 at 1:32 PM, James F.

With the file 'GSE21111_series_matrix.txt.gz' the function getGEO will return a list of ExpressionSet(s) which you can query for phenotypic data using pData or phenoData. It would be easier to simply use: gse <- getGEO("GSE21111") Best, J. > > > On Thu, May 19, 2011 at 1:32 PM, James F.
