    which is the right conversion for Solid?

    Hi, I have been using several scripts from maq, fastq-mcf and galaxy to transform my csfasta & qual data into fastq (in base space). all of them gave me the same sequence, but when I tried to do it manually based on the code given by Solid I get a different sequence. I tried a script that I found in a forum and is the only script that has coincide with my translation. Can anyone tell me which is the right conversion and which one has a frame shift please?

    The csfasta to fastq converters will not decode the sequence to basespace. The manual way is the correct conversion, but it is likely not the correct sequence given the high error rate.

      Thanks Chiper, I am also filtering the low quality bases on both extremes and removing all the reads with non-called bases

        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.
