I am attempting to use BayesPeak. I have a file of mapped reads from a ChIP-seq experiment and from a negative control in bed6 format. 

The following is my output: 


> raw.output <- bayespeak("chip.bed", "negative.bed", chr = "chr", start = 80000, end = 100000, job.size = 1000)
Read 23148733 records

  error in evaluating the argument 'x' in selecting a method for function 'var': Error in tr$"+"$norm[x[1]:x[2]] : 
  only 0's may be mixed with negative subscripts

I am not sure what is causing this error. Does anyone have some insight into this? I have pasted my session info below.

Hi - Sorry to hear that. Would you mind posting the top couple of lines from the bed files, so that I can try to reproduce the error? Also, please check that you correctly specified the argument:

chr = "chr"

(This is only correct if you have intentionally made a chromosome called "chr" in your bed file.) Thanks

Thank you for your response. I've supplied the first ten lines from my bed file below. 

chr  0       50      chip_259:H5KJLBCXX:2:2112:14750:28587   255     +
chr  0       50      chip_259:H5KJLBCXX:1:1104:19559:73230   255     +
chr  0       50      chip_259:H5KJLBCXX:2:1214:13540:77997   255     +
chr  0       49      chip_259:H5KJLBCXX:2:2115:5666:26092    255     +

I'm afraid I was unable to reproduce the error. Could you try upgrading to the latest version of R and BayesPeak (I used 3.2.2 and 1.20.0, respectively) please? If you still get the error, try checking that the IRanges object produced by read.bed("chip.bed") makes sense. If this seems OK, then please email me an example of a bed file that causes the error. Thanks!
