    Reg Picard MarkDuplicates

    Hi

    I am beginner in python. I am trying to automate the process of variant calling for the whole genome sequencing data for plants in ubuntu. We wrote commands for each software (by giving path) and integrated all software's in python. I am having a problem when i execute the script, where the script file could not run picard tools Mark Duplicates. It did not give any error but process wont continue after that, whereas when i use same tool, picard markduplicates in terminal its working fine without any error. Can anyone help me in trouble shooting this.

    Example script that we wrote

    import subprocess,os,commands

    m=raw_input("Enter the project destination")

    os.environ["JAVA_HOME"]="/usr/java/jdk1.8.0_121/lib/visualvm/platform/modules"

    os.chdir('/home/sukesh/picard-tools')

    os.system('java -jar picard.jar MarkDuplicates I='+m+'/6SAMTOBAM/sortIRGSP.bam
    O='+m+'/7MARKDUPS/dups.bam REMOVE_DUPLICATES=false METRICS_FILE=metricN.log ASSUME_SORTED=True VALIDATION_STRINGENCY=LENIENT')

    os.chdir('/home/Downloads')

    Or is there any other tool which can mark duplicates other than samtools which will be more helpful?

    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.
