    As manual said "read length can be 1024". Do you mean seq quality will be ignored when it is a long read? If so, what's the max length? Only n mode considering seq quality, will it affect v mode?

    Dear All,
    When aligning long reads such as >75bp, which mode of Bowtie do you use? -n mode mapping the first L (default 28) bp of a read while -v mode maps the whole read allowing no more than v mismatch. I'm wondering which method is more suitable for the long read alignment.
    Many thanks.

    Best,
    IMO, if you want to allow more number of mismatches, you can only use n mode with large e value, since both n or v option only allow at most 3 mismatches. Say, you can set -n 3 with larger e value.

    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
