Hello All,
I apologize if this email shows up twice to the mailing list.
I'm trying to use ChIPpeakAnno to identify the annotation of ChIP-Seq
peaks
for an organism that does not have an annotation package. I have used
makeTranscriptDbFromGFF to create a transcriptDb object and trying to
pass
it as the annotation data for annotatePeakInBatch function. However, I
suppose it is not the way to handle that. I tried googling quite a bit
but
no luck.
Is there a way to convert TranscriptDb object to RangedData?
The error I ended up with:
Error in annotatePeakInBatch(t.rangedData, AnnotationData = ep, :
AnnotationData needs to be RangedData object
Please let me know how to approach this issue.
Thanks for any help.
Alan
Here is my code and sessionInfo:
library(ChIPpeakAnno)
test.rangedData = BED2RangedData("ChIP-test.bed")
test.rangedData
txdb <- makeTranscriptDbFromGFF(file="spgen.gtf", format="gtf",
exonRankAttributeName="exon_number", dataSource=paste("eunam",sep=""),
species="epp")
saveDb(txdb,file="spgenGTF.sqlite")
ep <- loadDb("spgenGTF.sqlite",)
annotatedPeakEP= annotatePeakInBatch(test.rangedData, AnnotationData =
ep,
output="both", maxgap=1000, multiple=TRUE)
Error in annotatePeakInBatch(test.rangedData, AnnotationData = ep, :
AnnotationData needs to be RangedData object
