I an new in micro array data analysis. I want to do the differential expression analysis of an Array Express data set (E-UMCU-11). But when I am using the command "AEset = ArrayExpress("E-UMCU-11") " The error given below is coming. I try to find out the solution in net and found "How to get the expression data of each gene from the ArrayExpress database.", Then I try to use E-UMCU-11.eSet.r but there is no such file with E-UMCU-11 data set. Please help me ..

The error is given below:

The row names should not be duplicated, as expected by the function. Try contacting ArrayExpress.
