    I assume you mean:
    Code:
    bowtie -v 3 -k 2 --sam /raid/references-and-indexes/hg19/bowtie-indexes/hg19 /raid/development/anusha/SRR203400.fastq | samtools view -S -F 0x4 -o /raid/development/anusha/SRR203400.bowtieold.flagtrnc.bam -
    Or something like that, which will write to a BAM file and ignore unaligned reads.

      Can anyone explain me how to look for the SNP's in IGV browser


      Thanks,
      Anusha.Ch
      I assume you mean "look at SNPs", since it would take forever to manually look for them in the whole genome. You should be able to answer that question yourself (hint, what should a SNP look like?).

        Fastq dump and finding the contiguous reads covered by at least one read

        Hi Everyone ,
        I have couple of questions . Can anybody explain me in detail answers

        1) When u are using fast dump if u want to output to specific place where you want what option in fastq dunpl wil give this.

        fastq-dump [options] [ -A ]
        fastq-dump [options]
        what is the accession in the option what for it used because if i gave without option A it worked. I am using shell script to automate my process i want the output to the place i wanted .
        I used above shell script it worked
        #!/bin/bash
        # generating a fastq file using fastq dump

        fastq-dump $2 $1
        but while running it came like this why ?


        anusha@cn1:/raid/development/anusha/python_test/shelltest> ./SRAtoBAM.sh /raid/development/anusha/python_test/shelltest/SRR203400.sra /raid/development/anusha/python_test/shelltest/SRR203400.fastq
        2013-10-01T22:02:53 fastq-dump.2.1.12 err: table not found while opening manager within database module - failed to open '/raid/development/anusha/python_test/shelltest/SRR203400.fastq'
        Written 16472407 spots for /raid/development/anusha/python_test/shelltest/SRR203400.sra
        Written 16472407 spots total

        2) what tools will give " contiguous reads covered by at least one read "


        Thanks so much in advance

        Thanks,
        Anusha.Ch

          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.
