Hi Team

I am evaluating my CpG island and annotating it. However, while doing the annotation I am getting the error. I also tried using example bed file shown in the methylKit documentation but the result is same.

        myDiff25p=getMethylDiff(myDiff,difference=25,qvalue=0.01)

        gene.obj=readTranscriptFeatures("C:/R-Data/Bismark_using/hgTables.bed.txt")    

        annotateWithGeneParts(as(myDiff25p,"GRanges"),gene.obj)

# please also include the results of running the following in an R session 
 > annotateWithGeneParts(as(myDiff25p.hyper,"GRanges"),gene.obj)

Hi

I resolved the problem. The error was coming because of Chromosome numbering. Bed files was having "Chr" which i removed and resolved the problem.
