Hi > mark.pathway.by.objects function pathway.id, object.id.list) { return(.SOAP(KEGGserver, "mark_pathway_by_objects", .soapArgs = list(pathwya_id = pathway.id, object_id_list = object.id.list), action = KEGGaction, xmlns = KEGGxmlns)) } I just wondered if the "pathwya_id" type in the above function will have any effect? (I don't know as I'm struggling to get this to work through my proxy) Mick

Hi, I am working on the normalization of microarrays with the method gcrma. I would like to know how to perform the two kinds of estimation of the background noise : Maximum likelihood Estimator and Bayes estimator. Is there an option which performs each of them ? Thank you for your help. Best regards,
