Thanks for your quick reply.

> table(probeAnno["5.index"] %in% featureNames(X))

FALSE
21152

What are feature names in probeAnno? Actually I used a new output file from 
the script you edited to generate probeAnno with no complain:

probeAnno <- 
posToProbeAnno("C:/from_DriveD/Chip-chip/Bultman/allChromExonerateOut_new.txt")
    Creating probeAnno mapping for chromosome 1 10 11 12 13 14 15 16 17 18 
19 2 3 4 5 6 7 8 9 X Y Done.
allChrs <- chromosomeNames(probeAnno)
genome(probeAnno) <- "M. musculus (mm9)"
arrayName(probeAnno) <- "2007-02-27_MM8_CpG_Island_Pro_Tiling"
