  • New to MALT

    Hey there!

    I'm new to using MALT and I'm confused about the mapping files. I think I want to use accession to taxonomy (-a2taxonomy) but I don't know where I should get that mapping file or how I know if it's compatible with my version of the database I'm using (for example NCBI's nt).

    I’ve found megan-nucl-Jan2021.db.zip at:

    as well as nucl_gb.accession2taxid.gz at:
    ftp://ftp.ncbi.nlm.nih.gov/pub/taxon...cession2taxid/
    However all the examples of malt-build I’ve seen have a .bin extension for the mapping file, so I’m not sure if these would work.

    I also noticed that the MALT manual says "The options -tre and -map are used to access the NCBI taxonomy, which is needed to perform a taxonomic analysis of the reads as they are aligned." in reference to the -tre $MALT/data/ncbi.tre.gz -map$MALT/data/ncbi.tre.gz options in the example, what are these files and where can I get them?

    Thanks in advance for any help!

    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.”
