Hi Bioconductors, is there anybody who has written a function to retrieve microarray experiments from ArrayExpress and convert them into an ExpressionSet or indeed a data package containg an ExpressionSet ?

Hi Wolfgang, The closest to this is probably the RMAGEML package which enables one to read MAGE-ML files from ArrayExpress and convert them into an ExpressionSet. However this package has limitations: one has to go to the ArrayExpress website and manually download the different MAGE-ML files that are needed, it only works for spotted arrays, and the MAGE- ML format is currently being replaced by a quite different format MAGE- TAB, for which the RMAGEML package can not be used anymore.
