    question about Solid data analysis using bowtie?


    hello ,everyone
    I am trying to run bowtie with the solid sequence data flower9_1_F3.csfasta and flower9_1_F3_QV.qual
    I built the bowtie-build -C index successfully and moved the generated index files to the Bowtie indexes subdirectory. I run the command:
    bowtie -n 3 --best --strata -a -e 150 -p 4 ../cDNA_reference/TAIR9_cdna -C -f flower9_1_F3.csfasta -Q flower9_1_F3_QV.qual --un fllower9-unmap > flower9-map &
    and the output i got is an error showing on console

    [wanglei@mu01 data]$ [wanglei@mu01 data]$ Too few quality values for read: 425_2031_2008_F3
    are you sure this is a FASTQ-int file?
    terminate called after throwing an instance of 'int'
    Too few quality values for read: 425_2042_1847_F3
    are you sure this is a FASTQ-int file?
    terminate called after throwing an instance of 'int'
    Too few quality values for read: 1277_2042_2013_F3
    are you sure this is a FASTQ-int file?
    Could you please help me to sort out this issue?
    thanks

        Truncated Qual file

        I have had this error when SAET failed and a truncated qual file was produced.

          Hey guys,
          How did you solve this problem ? Could you please help me with this ?
          I am also getting this error, when using tophat mapping on colorspace file.

          This is my command: [Works fine until half-way]

          tophat --output-dir /results --color -p 8 --no-coverage-search /bowtie_alignment_reference/mm9_c F3.csfasta F3.QV.qual


          I get this error:
          Mapping left_kept_reads_seg1 to genome mm9_c with Bowtie (1/3)
          Mapping left_kept_reads_seg2 to genome mm9_c with Bowtie (2/3)
          Mapping left_kept_reads_seg3 to genome mm9_c with Bowtie (3/3)

          [2012-10-20 22:11:02] Mapping right_kept_reads to genome mm9_c with Bowtie

          Error running bowtie:

          are you sure this is a FASTQ-int file?

            Did anyone of you solve this problem?
            I have exactly the same problem now.

            Mapping left_kept_reads to genome GRCh37_gatk_colorspace with Bowtie
            Mapping left_kept_reads_seg1 to genome GRCh37_gatk_colorspace with Bowtie (1/2)
            Mapping left_kept_reads_seg2 to genome GRCh37_gatk_colorspace with Bowtie (2/2)
            Mapping right_kept_reads to genome GRCh37_gatk_colorspace with Bowtie
            [FAILED]
            Error running bowtie:
            Too few quality values for read: 28 I
            are you sure this is a FASTQ-int file?
            terminate called after throwing an instance of 'int'

            All 4 files are exactly 200000 lines (so 100000 reads). Mapping the left reads works, but when mapping the right reads it fails...

            [EDIT]
            For anyone who has this error too, check whether you have added the --quals option, also check the command on order of files (first all csfasta files than the qual files). This solved my error...

              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,...

              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
