  • denovo on sam format

    Dear All,

    I have alignment results in bam file which includes pair-end , mate-pair reads in different lengths, does anybody know Soap or other denovo program can handle bam file directly or I have to use the "raw" reads files? Can I mixture the reads in one file for denovo?

    Many thanks!

    Recent versions of Velvet can read directly from SAM and BAM files; it extracts qnames, pairing information, and sequence data, which is all it's interested in. The files must be sorted by (or at least grouped by) read name, but -- unlike other formats read by Velvet -- paired and unpaired reads can be mixed. See Daniel's announcement for details.

    I don't know about other assemblers and SAM/BAM. You could of course use a tool like Picard's SamToFastq to reconstitute a more widely-read-by-assemblers format from your BAM files.

        Multiomics Techniques Advancing Disease Research
        by seqadmin


        New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”

        A major leap in the field has
