    How to plot the QV distribution of SOLiD data ? Is there any tool available?

      have you tried fastqc?

      http://hts.rutgers.edu/filter/ is also useful in assessing QV distribution

        Is anyone using FastQC on 5500 data? Apparently I need to convert the .csfasta/.qual files first to .fastq. There are several csfasta2fastq tools out there, but I can't get a single one to work on my data. My data is divided in 4 files, F3 csfasta/qual and F5_RNA csfasta/qual. Why, I don't know (yet). The versions of csfasta2qual I found don't like this very much. Or is there a different QV analysis tool I should be using?

          hi golharam,
          use the SOLiD2std.pl to change the csfasta and qual files to standard fastq files.
          then run fastqc to view boxplots of quality data, etc..
          II think the qual file must be <prefix>.qual (not .QV)

          cheers

            golharam - you can try prinseq as well.



            The initial results are ok but the real beauty is in the graph output file, which can also be produced online.

            Another way to use FastQC is by first aligning and then reading the BAM files.

              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

              New Genomics Technologies Take Aim at Long-Standing Limits
              by SEQadmin2


              Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

              We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
