Tutorials

Each walkthrough prepares the data with command-line tools, from sequences to an alignment, a tree and annotations, and ends on a link that opens the result in JBrowseMSA.

Phylogenies and metadata

Genomes and recombination

R, Python, JBrowse and web pages

  • The GDSGGP motif of nine serine proteases beside five relatives that read A, M, Y or G at the catalytic serine A protease family in R

    Fourteen peptidase S1 domains from UniProt, aligned with DECIPHER, a tree from ape, and two layers R computes.

  • Antigenic site B across 25 influenza vaccine strains in year order, the letters under the two bands turning over every few rows Influenza drift in a notebook

    25 H3N2 vaccine strains from 1968 to 2022 as one hemagglutinin alignment in Jupyter, with a count of how often each column changed.

  • One JBrowse session holding the TP53 gene with ClinVar, the p53 ortholog alignment and the AlphaFold structure, connected JBrowse 2 integration

    The same alignment and tree opened inside JBrowse 2 beside a genome view and an AlphaFold structure, each session a single URL.

  • A web page showing the NLRP1 alignment as a static figure, with an Explore the alignment button in its corner An alignment on your own page, static first

    The NLRP1 family as an SVG the CLI draws, 6.6 KB gzipped, swapped for the live viewer on a click, measured with Lighthouse against loading the viewer at once.
