§ 01 — How it works

Metaproteomics is hard. Conduit makes it easy.

The search space defines everything downstream. Conduit builds it, then carries the run the rest of the way.

  1. 01

    Spectra

    .raw · .mzML

    Bring your DIA runs and a sample sheet.

  2. 02

    Search space

    8 strategies

    Decide which proteins could be there.

  3. 03

    Search

    DIA-NN · containerised

    Identify, quantify, annotate. Same result on any machine.

  4. 04

    Summit

    Explore · R or GUI

    Taxonomy, function and statistics, code-free.

§ 03 — Search space

Your experiment. Your search space.

Eight ways to answer the first question: what proteins could be here?


    § 04 — Ecosystem

    Four tools. One workflow.


    § 05 — Quickstart

    Two ways in. Pick your altitude.

    The easy way · no command line

    Use the Basecamp app

    § 06 — Requirements

    What you need. What people ask.

    SystemLinux, or macOS / Windows via Basecamp
    Hardware128 GB RAM · 24 coresmore for very large search spaces
    Storage50–200 GB reference databases
    SoftwareSnakemake · Apptainer · DIA-NN
    Input.raw or .mzML + sample sheet
    LicenseMIT, every component
    Do I need Linux?

    Only for the command line. Basecamp runs on macOS, Windows, and Linux and manages the Linux environment Ascent needs — natively, in a VM, or on a remote workstation over SSH. Running Ascent directly needs a Linux workstation, lab server, or SLURM cluster.

    How big a machine?

    A minimum of 128 GB RAM and 24 cores. Broad peptidotyping passes or big genome catalogs can need far more, so plan on an HPC node for those. Raw Astral files are around 7 GB each, and reference databases for some strategies reach 50–200 GB.

    What do I have to install?

    Snakemake (≥ 7.0) and Apptainer (≥ 1.1). Everything else — R, Python, MetaPhlAn, Bakta, eggNOG-mapper — ships in pinned containers. DIA-NN is downloaded separately under its own licence: free for academic use, while commercial use needs a licence from its authors.

    No genomes of my own?

    The genome strategies can pull a curated MGnify genome catalog — genomes and taxonomy included — by setting genome_download_source: mgnify and mgnify_catalog: human-gut/v2.0.2.

    Where do I get help?

    Open an issue on the repository it concerns: Ascent, Summit, conduitR, or Basecamp.

    How is it licensed and funded?

    Every Conduit component is released under the MIT License; third-party tools such as DIA-NN keep their own (notices). Conduit is supported by the UCSD Health Sciences Collaborative Center for Proteomics.
