Dingxia,
Please use the following command (skip =1 is added). Please keep the
thread in the Bioconductor list so that others can contribute and/or
benefit. Thanks!
MyPeakList = BED2RangedData(read.table("TSpeakList.bed", sep=
"\t",header=FALSE, skip=1))
Best regards,
Julie

Hi, Lihua,
Thanks for the reply. I tried your code, it didn't work for my file.
The error messages are like this:
> MyPeakList = BED2RangedData(read.table("TSpeakList.bed", sep=
"\t",header=FALSE))
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,
na.strings, :
line 1 did not have 5 elements
I guess the problem is the format of my .bed. I got this file after
using the mosaic peak caller package. The first lines of this .bed
file are like this:
track name=mosaicsPeaks description="MOSAiCS peaks" useScore=1
chrI2380023999 MOSAiCS_peak142
chrI158400 158599MOSAiCS_peak126
chrI223000 223399MOSAiCS_peak289
chrI334600 335399MOSAiCS_peak848.5
I also attached this file here, I hope it can help you understand my
data structure. If you need more information about my file, please let
me know, I'll try my best. Thanks for the help.
Best wishes.

Dingxia,
If your peak file is in bed format, you could just use the following
command
to create RangedData.
MyPeakList = BED2RangedData(read.table("peak.bed", sep=
"\t",header=FALSE))
Best regards,
Julie
