  • Compare results from different aligners (SAM files)

    I would like to take 2 SAM files that are the results of alignment of the same input by different aligners and compare them.
    Does anyone know of a code that already does that?

    Thanks,

    Guy.

    I already asked that and noone could provide me with any useful code, see
    Discussion of next-gen sequencing related bioinformatics: resources, algorithms, open source efforts, etc

    So I hope someone might give a positive answer here.

      Define "Compare"

      Maybe if you could specify what you want to compare there would be a bigger chance that someone will provide more useful information.

      To me it sounds like something you would do on your own with a little script in whatever programming language you like best
      You could for example use samtools to sort both files and then use awk or whatever you like to check which reads are aligned in the same spot and which are not o.O

        I'm interested too.

        I will be looking at this sometime in the near future (before August), I'll post whatever methods I use/come up with then.

          I came across this utility


          $bam diff --in1 file1.sam/bam --in2 file2.sam/bam --out file1.fil2.diff.sam/bam

          This will create three sam or bam files. proceeding from there...

            Exploring the Dynamics of the Tumor Microenvironment
            by seqadmin




            The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

            Exploring Human Diversity Through Large-Scale Omics
            by seqadmin


            In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
