Does the `matchPWM` function in the Biostrings package do what you're

Can you explain this a bit more? Do you want to, say, use a GRanges
object to query what "type" of genomic annotation is there (intron,
cds, utr, etc)?
If that's the case, at the previous bioc workshop in Feb, it seemed
like several people hacked up their own way to do things like that.
I believe Valerie has put something "more official" together somewhere
in her "VariantAnnotation" package that you might like to use.
