    If the genome you are mapping to is a bacterium or lower eukaryote (30 to 100 MB), give MIRA a try. I wrote the mapping routines to behave consistently for exactly these cases.

    Thanks. But do you have another idea?

    "Another important note: because reads produced from the 454 technology inherently contain false indels, the realigner will not currently work with them (or with reads from similar technologies)."

    deletion mapping problem

    Hello,

    I'm mapping 454 reads against a reference genome using bwa and then create sorted bam files using Samtools.

    However, most my samples do have only one copy of a 9bp motif, whereas the reference has two. In some reads of my sequence data the motif will be followed by gaps and in some the gaps will be followed by the motif and in the end the consensus will call it as a tandem repeat.

    I tried to use GATK for realignment, but it didn't work. Has anyone used GATK for this purpose successfully? Or does anyone have other ideas how to solve the problem? others than de-novo assembly?

    I'm building up a fully automized pipeline so I use command line based software and scripts.

    Help would be highly appreciated!

    Thanks,
    Stefan

    Recent Advances in Sequencing Analysis Tools
    by seqadmin


    The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...
