    Problem converting solid2fastq with Barcode

    Hi NGS users,
    I always use solid2fastq 0.6.4e (from bfast+bwa-0.6.4e) to convert csfasta2fastq (both single read and paired end) in this way:

    > solid2fastq -o output -b sample_F3.csfasta sample_F5-P2.csfasta sample_F3_QV.qual sample_F5-P2_QV.qual

    and it's run perfectly, generating two file (output.read1.fastq and output.read2.fastq)

    Now, I have SOLiD samples in PE with barcode.
    But when I run

    > solid2fastq -o output -b sample_F3_1_23.csfasta sample_F5-BC_1_23.csfasta sample_F3_QV_1_23.qual sample_F5-BC_QV_1_23.qual

    the program returns me only a single fastq containing only the reads of F5-BC strands. (output.single.fastq)

    How can I fix this problem?
    Thanx a lot,
    ME

    Post your question to [email protected] and give the first few reads in both files.

      I posted the question to bfast-help.
      These are the reads:

          I don't really see why you have to enter both pairs in a single solid2fastq run, since each pair will output a single fastq file. or does solid2fastq perform any kind of extra check when entering single or paired-end data? wouldn't it be easier to call them separately, ie
          Code:
          solid2fastq -o output sample_F3.csfasta sample_F3_QV.qual
          solid2fastq -o output sample_F5-P2.csfasta sample_F5-P2_QV.qual
          I also used to use solid2fastq v0.6.4 to convert my SOLiD output, but I never saw that "-b" option, nor even in the current v0.6.5. did it work for you? what exactly was it doing?

            The "-b" option is in the bfast+bwa-0.6.4e version.

              Hi I have bwa-0.5.9/solid2fastq.pl version. I have two files SolF3.csfasta & SolF3_QV.qual which i want to convert in 'fastq'. After running the command as :

              perl solid2fastq.pl Sol SolTest

              I am getting the file SolTest.single.fastq.gz but with no reads in file after i unzip it, whereas i have good and equivalent amount of reads in my input read (*F3.csfasta) and qual (*F3_QV.qual) file. Can someone explain me the reason if ever stuck in similar problem.


              Strange to say the same command is working fine with another set of file.

                this thread was about using solid2fastq with barcodes, so I would suggest you to open a new thread asking for help. in it, I guess the first thing you would be noticed is that it is much faster to use the C implementation of solid2fastq rather than the perl script, and that the typical usage command would be something like this:
                Code:
                solid2fastq -o SolF3 SolF3.csfasta SolF3_QV.qual
                which would generate a SolF3.fastq file with all SolF3 reads with their corresponding qualities.

                  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.
