Hi Eugene, I don't know of an easy answer. A difficult answer might be the XML package, with things like > library(XML) > ## This is from ArrayExpresss > fl <- file.path("/loc/mtmorgan/tmp/E-MEXP-140", + "Auxin_induced_effects_investigated_using_bead- purified_probe_arrays_1_qtd.xml") > res <- xmlTreeParse(fl,useInternalNode=TRUE) > > ## How many reporters? > reporters <- getNodeSet(res, "//Reporter_ref") > length(reporters) [1] 19328 > ## each reporter includes an encoded identifier > head(sapply(reporters, xmlGetAttr, "identifier")) [1] "R:A-MEXP-68:96103_2" "R:A-MEXP-68:96103_4" "R:A-MEXP-68:96103_6" [4] "R:A-MEXP-68:96103_8" "R:A-MEXP-68:96103_26" "R:A-MEXP-68:96103_28" > > ## 'MeasuredBioAssayData stores cel-file level data; in AE these are > ## usually stored as DataExternal, i.e., tab- or > ## whitespace-delimited files. mbad <- getNodeSet(res, "//MeasuredBioAssayData") > sapply(sapply(mbad, getNodeSet, "//DataExternal"), + xmlGetAttr, "filenameURI") [1] "Untreated-vs-30min.txt" "30min-vs-Untreated.txt" [3] "Untreated-vs-120min.txt" "120min-vs-Untreated.txt" [5] "Untreated-vs-240min.txt" "240min-vs-Untreated.txt" [7] "Untreated-vs-Untreated.txt" to extract relevant information from the XML. This is likely to end up requiring detailed knowledge of MAGE-ML and of Bioconductor data structures.
