    Crossbow 1.2.1 On Hadoop - question

    I am running this on a CDH3 cluster currently.

    Crossbow prerequisites mention the following among others:

    1. A bowtie v0.12.8 executable must exist at the same path on all cluster nodes (including the master).
    2. A Crossbow-customized version of soapsnp v1.02 must be installed

    I cannot seem to find these specific functions. Would newer versions of these components work - Bowtie-1.0.0 and SOAPsnp-v1.03?

    Also, running this command:
    ./cb_hadoop --preprocess --input=hdfs:///crossbow/example/e_coli/small.manifest --output=hdfs:///crossbow/example/e_coli/output_small --reference=hdfs:///crossbow-refs/e_coli.jar --all-haploids --streaming-jar=/usr/lib/hadoop-0.20/contrib/streaming/hadoop-streaming-0.20.jar

    And consistently getting this error:
    at SRR014475.fastq_1.out.gz | /usr/bin/md5sum | cut -d' ' -f 1
    Error: No command named `-version' was found. Perhaps you meant `hadoop version'
    hadoop could not be found in HADOOP_HOME or PATH; please specify --hadoop

    As per Michael S, I have created a symlink for hadoop streaming jar to hadoop-streaming-0.20.jar and HADOOP_HOME is set to /usr/lib/hadoop-0.20

    Any help is appreciated! I have unsuccessfully tried to run this on CDH4 and IDH clusters before and attempting to get to a running baseline with CDH3 as it was only tested on this version.

    Thanks.

    Thanks to Micheal S, I was able to obtain the specific bowtie 0.12.8 and everything seems to work fine. Hadoop errors are really bogus!

      Thanks for sahring for this valuble information and it is useful for hadoop learners.hadoop online trainings also provides best http://hadooponlinetrainings.com/had...line-training/hadoop online training

        16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
        by SEQadmin2




        NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
