Dear all,

I am trying to use the ygs98 package to annotate the probesets from the
YGS98 microarray platform, however, I figure out that the annotation package
does not provide any information about the Locus Link ID / ENTREZ ID:

> ls("package:ygs98")
 [1] "ygs98"             "ygs98ALIAS"        "ygs98CHR"
 [4] "ygs98CHRLENGTHS"   "ygs98CHRLOC"       "ygs98DESCRIPTION"
 [7] "ygs98ENZYME"       "ygs98ENZYME2PROBE" "ygs98GENENAME"
[10] "ygs98GO"           "ygs98GO2ALLPROBES" "ygs98GO2PROBE"
[13] "ygs98LOCUSID"      "ygs98MAPCOUNTS"    "ygs98ORF"
[16] "ygs98ORGANISM"     "ygs98PATH"         "ygs98PATH2PROBE"
[19] "ygs98PMID"         "ygs98PMID2PROBE"   "ygs98QC"
[22] "ygs98QCDATA"

The package does contain ygs98LOCUSID, but when I try to get information
from it:

> unlist(as.list(ygs98LOCUSID))
Error in function ()  : object "ygs98ENTREZID" not found
In addition: Warning message:
'ygs98LOCUSID' is deprecated.
Use 'ygs98ENTREZID' instead.
See help("Deprecated")

However, ygs98ENTREZID in fact does not exist.......



Could anyone show me some ways I could find the locus link / entrezid ID
directly if I have a set of probesets from the ygs98 microarray platform ?

Thanks a lot,
Alex-
