Hi,all:
I have a long list of coordinates, which was created by the following code:
testIranges<- IRanges(start=currCoorList $starts,
        end=currCoorLis$ends)

   testTrack<-GenomicData(testIranges,chrom=currCoorList$chr,
        strand=currCoorList$strand,genome="mm9")

I could then export the testTrack into .bed file and upload in the UCSC
genome browser and get the sequences of the listed coordinate
But I was thinking if there is a function from rtracklayer to retrieve
sequence directly. I checked the rtracklayer reference manual, there was a
function getSeq. But I tried to use the following code:

track(session,"test")<-testTrack
seq<-getSeq(session,range(session),track="testTrack")

 it told me

Error: could not find function "getSeq"


Can anyone give me a hand? Thanks!
