    coveragebed output result problem

    Hi,

    I'm running coveragebed to calculate the number of read count in each transcript of tophat alignment result by using the following command:
    Code:
    /bedtool/arq5x-bedtools-26a87ab/bin/coverageBed -abam accepted_hits.bam -b transcripts.bed > transcripts.cov.txt 
    cat transcripts.cov.txt
    gi|224589800|ref|NC_000001.10|  8378168 8404227 "ENSG00000162426"       [B]70      1059    26059   0.0406386[/B]
    Does anybody knows what is the 70, 1059, 26059, 0.0406386 represent?
    I know that 0.0406386 is obtained from 1059/26059.
    Is it 1059 refer to total number of read aligned to the transcript and 26059 represent the transcript length? How about 70?
    Kindly correct me if I'm wrong.
    Thanks for any advice.

    If you type "coverageBed -h", the last few lines describe the output format.

    Code:
    Default Output:  
    	 After each entry in B, reports: 
    	   1) The number of features in A that overlapped the B interval.
    	   2) The number of bases in B that had non-zero coverage.
    	   3) The length of the entry in B.
    	   4) The fraction of bases in B that had non-zero coverage.

        From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
        by SEQadmin2


        Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


        The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

        Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
        by SEQadmin2

        Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


        Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
