I don't know of any path on Windows that looks like //Marvel-xms4rmgc/festplatte/A2M Lab/01 Customers/AKH/Erowic/data/filename.cel Do you perhaps mean something like C:/Marvel-xms4rmgc/festplatte/A2M Lab/01 Customers/AKH/Erowic/data/filename.cel? The error you see is R complaining that it cannot find the files as written. Best, Jim James W. MacDonald Affymetrix and cDNA Microarray Core University of Michigan Cancer Center 1500 E.
