Dear Julie:
I would appreciate your help with the following matter:
1, When I do analysis of my data using the program "ExonPlusUtr" to
annotate my data, I have confused the output "IncludeFeature" what is
means for this? what's difference between the
inside and IncludeFeature?
IncludeFeature: the peak range includes the entire feature range.
If the feature is an exon, then the peak range includes the entire
exon range. So the peak range is larger than the feature range.
Inside : peak resides inside the feature range, which means that
the peak range is shorter than the feature range.
2, If the CHIPpeakAnno package can be used to annotate the Exon and
Intron, 5UTR and 3UTR separately?
Yes, you can can. Here are a few examples assuming myPeakList is your
peaks as RangedData. For details, please type ?getAnnotation and
?annotatePeakInBatch.
mart<-useMart(biomart="ensembl",dataset="hsapiens_gene_ensembl")
Annotation.Exon = getAnnotation(mart, featureType="Exon")
Annotation.5utr = getAnnotation(mart, featureType= "5utr")
Annotation.3utr = getAnnotation(mart, featureType= "3utr")
annotatedPeak.Exon = annotatePeakInBatch(myPeakList,
AnnotationData=Annotation.Exon)
annotatedPeak.5utr = annotatePeakInBatch(myPeakList,
AnnotationData=Annotation.5utr)
annotatedPeak.3utr = annotatePeakInBatch(myPeakList,
AnnotationData=Annotation.3utr)
Best Regards,
Xianyong

Hi, Dear Dr.Zhu:
I got nice results by using your software, and I am still using this
soft ware to analyze other data, now I have the following problem and
tried two days, I
can't figured out, would you please help me to solve this problem, I
am really appreciate! since the file is bigger than 60 Mb (after
compressed), I can't send it
directly.
When I used the CHIPAnno software to analysis my data, as problem
always exist as following:
> test1.bed=read.table("/Users/xm5/Downloads/ChIPpeakAnno/data/CHIPJ3.
bed", sep="\t", skip=0, header=FALSE)
> CHIPJ3 = BED2RangedData(test1.bed, header=FALSE)
> data(TSS.human.GRCh37)
> annotatedPeak = annotatePeakInBatch(CHIPJ3,
AnnotationData=TSS.human.GRCh37)
Error: cannot allocate vector of size 14.4 Mb
R(365,0xa0416540) malloc: *** mmap(size=15118336) failed (error
code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
I don't know what's reason, and I checked the file using other
program, it looks OK, would you please help me to figure out, I
appreciate your nice help please see the
attached file that I used for this analysis.
Best wishes,
Xianyong
