  • No snp found in chrM?

    Dear All,

    It's hard to find SNPs in mitochondrial by samtools default setting, like D=100. I have explored several human genome data, NA18507, SJK, Venter, Watson, no snps found in ChrM.

    For Chinese han, e.g YH genome, soap found 36 SNPs in chrM, seven are novel, samtools found nothing.

    Can anyone explain? Thanks

    Don't set a maximum depth in filtering. You usually get thousands folds of coverage on chrM.

      Thanks Ih3, so your suggestion is not setting maximum depth only for chrM? Watson has ~2m SNPs got from www.jimwatsonsequence.cshl.edu, in some literature supposed >3m snps in watson, what's the reason for that? filtering ?

      Thanks

        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.”
