    Pindel multi sample run

    Hi All,

    I am running Pindel with multiple samples together and it's certainly giving some amazing results. Thanks to Kai Ye for such a nice tool. Now I have a mixed bag of bam files produced from sequences generated in different batches. My question is: can I use multiple bam files from different batches together in Pindel? Will the CNV predictions be affected by different coverages of bam files from different batches? If yes, what should I do in this case? Should I just run the bam files from the same batch together? Or does it not really matter? I hope my questions are making some sense.

    Many thanks in advance.

    Regards.

    Pindel combines read-pair and split-read, which are also affected by the amount of data at any given region. You can certainly mix bam files from different batches and Pindel will find the variants as long as there is any supporting evidence in one sample and appear in other samples in the cohort.

    when you run pindel on a large amount of samples, please use -w to control memory usage.

      Hi Kai Ye,

      Thanks for the reply. It makes more sense now.

      Regards

        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.
