    Correct options for CNVnator

    Greetings,

    I'm trying to run CNVnator on a cohort of ~300 BAM files.

    For testing purposes I'm trying to run it on just 3 BAM files first.
    Here are the commands I'm running:

    Code:
    export HS37d5=/data/fastas/hs37d5
    
    cnvnator -root chr22.root -genome GRCh37 -chrom 22 -tree \
    	/nfs/wgs30x/bam.files/samp1.bam \
    	/nfs/wgs30x/bam.files/samp2.bam \
    	/nfs/wgs30x/bam.files/samp3.bam;
    
    cnvnator -root chr22.root -genome GRCh37 -chrom 22 -his 1000 -d $HS37D5
    
    cnvnator -root chr22.root -genome GRCh37 -chrom 22 -stat 1000
    
    cnvnator -root chr22.root -genome GRCh37 -chrom 22 -partition 1000
    
    cnvnator -root chr22.root -genome GRCh37 -chrom 22 -call 1000 > chr22.cnvnator.out

    Now all of this runs and I don't get an error (as far as I can tell).
    The last command I try is:

    Code:
    cnvnator -pe /nfs/wgs30x/bam.files/samp1.bam \
       /nfs/wgs30x/bam.files/samp2.bam \
       /nfs/wgs30x/bam.files/samp3.bam \
       -qual 20 -over 0.8 -root chr22.root -f chr22.support_reads;
    This command never finishes. I left it running for 36 hours and it didn't produce anything.

    I believe I'm screwing up the cnvnator -pe command but I can't figure out what the correct command should be.

    Using the cnvnator2VCF.pl produces a VCF file but it doesn't contain any read count information.

    Does anyone have any suggestions as to what I'm doing wrong?
    In case it helps I'm using CNVnator v0.4 (latest download from github).
    The system is a RHEL 7.2 box fully patched.

    Thank you in advance for any and all help.

    Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by SEQadmin2


    I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.


    Here are nine questions we think about, in roughly the order they matter, before...

    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.
