  • gatk bam is malformed

    Hi,
    I got the following error message after invoking gatk

    ERROR MESSAGE: SAM/BAM file /home/carolw/NGS/data/SRR062641.filt.marked.bam is malformed: SAM file doesn't have any read groups defined in the header.

    but I just got the MAPQ should be 0 for unmapped error when I ran bwa to generate sam and bam files. according to the forums, this error should be ignored. So whether the gatk problem comes from the bwa problem or warning or not, how to solve the problem?

    Please see the attached file for the outputs of bwa and gatk

    Look forward to your reply,

    Carol

    It says there are no read groups. Did you run bwa so that it would add read groups? Did you run a program to add read groups in after the fact?

    If the answer to those questions is "no" or "I don't know" then your problem is likely there.

      I added read groups when calling bwa.

      Now I get 2 different error messages when I run gatk

      If I use the output of picard markedduplicate, I get error message on unindexed bam file whereas the bam file is already indexed as it is already generated by picard samsort before invoking picard markedduplicate. bai file exist too.

      And if I use the output of picard sortsam directly, I get

        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...

        Essential Discoveries and Tools in Epitranscriptomics
        by seqadmin




        The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
