A question about bam file

[NJU-Bio-Info]

Hello, such an amazing GRO-seq mediated TU identification tool. When I used groHMM, I found that you bam file is different from mine so I received an error log:

Error in Fp[[i]] + 1 : non-numeric argument to binary operator

• my bam file format after import into R:

GRanges object with 6 ranges and 0 metadata columns:
      seqnames      ranges strand
         <Rle>   <IRanges>  <Rle>
  [1]     chr1 13934-13984      -

Have noticed the difference in "ranges" column, so do you mean that the ranges should be points rather than range?
