Dear List, Can anyone help me with the Agi4x44PreProcess - filtering probe function. I am not sure what I am overlooking. The error message says, "Error in filter.probes(aa, control = TRUE, wellaboveBG = TRUE, isfound = TRUE, : 'targets' is missing". Does this mean, my data files do not have the filtering parameters or it does not recognize the files. If I specify the file name, then it is not recognizing a mandatory column eventhough it is specified in the file."Error in filter.control(ddNORM, ManuelaGO, targets, annotation.package) : 'targets' needs 'GErep' field" I have pasted the session info for reference. Thank you very much in advance.
