Dear all,

I have used CopywriteR package with sequencing data and got an error.

Because I previously got a successful result with a different set of bam files, I think the problem would be the bam list (or some of the bam files), but I don't figure out what exactly is the problem.

My script, error messages and sessionInfo() are attached below.

Script:

library(CopywriteR)

BAMlist="PATH/TO/BAMlist.txt"

ref="PATH/TO/CONTROL.bam"

data.folder="PATH/TO/DATAFOLDER"
bin.size=50000
preCopywriteR(output.folder=file.path(data.folder),bin.size=bin.size,ref.genome="hg19")

bp.param=SnowParam(workers=10, type="SOCK")

samples=readLines(BAMlist)

samples=c(samples,ref)
controls=c(rep(ref,length(samples)))

sample.control=data.frame(samples, controls)

CopywriteR(sample.control=sample.control,
           destination.folder=file.path(data.folder),
           reference.folder=file.path(data.folder, "hg19_50kb"), bp.param=bp.param)

Error messages:

Error in .Method(..., deparse.level = deparse.level) :

In addition: Warning messages:

Based on the error output (" '-' not meaningful for factors"), I'm guessing that the function doesn't like some of the names in

BAMlist.txt. Can you print a `head` of that file?

Keith,

Thank you for your reply. The head (n=5) of BAMlist.txt is:

/home/tom/ngs/data/output/barcode/160405_Target/bam/s_TA_C001D/s_TA_C001D.markdup.bam
/home/tom/ngs/data/output/barcode/160405_Target/bam/s_TA_C002D/s_TA_C002D.markdup.bam
/home/tom/ngs/data/output/barcode/160405_Target/bam/s_TA_C003D/s_TA_C003D.markdup.bam
/home/tom/ngs/data/output/barcode/160405_Target/bam/s_TA_C004D/s_TA_C004D.markdup.bam

I looked inside the Copywriter.log file and it ended with:

INFO [2016-07-12 14:35:29] remote-error in value[[3L]](cond): failed to open BamFile: file(s) do not exist:
  ‘XXX(one of my bam files).bam’
I corrected the wrong path and then CopywriteR() ended successfully.
