    alignment software and ref sequence

    We are currently using MAQ to align our Solexa reads to our reference sequence. Does anyone know if MAQ can also tell me which parts of my reference sequence have no reads aligned to them? If not, can anyone suggest a program that can tell me this info? Thanks!

    Pretty sure MAQ can't, and a quick scan of the man page didn't yield anything.

    Have you tried one of the visualization tools? Only one I know off the top of my head is tablet, but unfortunately haven't had a chance to play with it myself:

      Actually, if I am not wrong, Maq`s pileup output has a column with the number of reads aligning at a given position, so you can get those with a 0 coverage out

      HTH,

        MIRA does. Can even give back a list of genes and/or intergenic regions which are hit by this (if references sequence has annotations like, e.g., a GenBank). If you're working with 20 to 30m reads, have a look at it.

        Beware, being a de-novo assembler, it's a lot more memory intensive than other mapping programs when used for mapping only.

        Regards,

        Disclaimer: I wrote MIRA. It's useful to me but it might not be for you. Feedback appreciated.

          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.
