Hello, I tried to update the annotations for Affymetrix' rgu34a chip using the buildDPkg.R. After some modifications I get as far as the flat file "rgu34aLL", but then fileToXML bails out with "Error in lapply(fileRead[, i], doMultValue, multSep, i) : subscript out of bounds Execution halted" Has anybody a version around that performs better?
