Bio tools

Home page

An interface for running arbitrary CLI applications for biology and chemistry. It focuses on tools with permissive licencing, and ones which are most popular. Available as a rust library, a python library, and a standalone CLI application.

Includes the most popular tools for structure prediction, sequence prediction, and drug design broadly. For example:

• AlphaFold 3
• ProteinMPNN and LigandMPNN
• Boltz-2 / BoltzGen
• RFdiffusion and RFantibody
• Chai-1
• Protenix
• BindCraft
• OpenDDE
• ImmuneBuilder
• ThermoMPNN

Around 35 more are covered; see Tool::ALL and tool_definitions::catalog for the full set, each with its own summary, license, and official links.

Handles the following tasks:

• Install
• Uninstall
• Run (Including abstractions over what inputs are accepted per tool)
• Check status

Quickstart

As a standalone CLI application

Install a prebuilt binary for Linux, Windows, or Mac from the Releases page, or build it with Cargo:

cargo install bio_tools

Either way you end up with bio_tools on your path.

As a Rust library

`cargo add bio_tools``

As a Python library

The PyPI distribution is named athanor_bio_tools. The module you import is bio_tools.

pip install athanor_bio_tools Or uv add athanor_bio_tools

Usage

Run the program with no parameters to see its functionality:

Usage:
  bio_tools [--root <directory>] install <tool>
  bio_tools [--root <directory>] uninstall <tool>
  bio_tools [--root <directory>] status-quick <tool>
  bio_tools [--root <directory>] status-full <tool>
  bio_tools [--root <directory>] run <tool> [-- <tool arguments...>]
  bio_tools [--root <directory>] list-quick
  bio_tools [--root <directory>] list-full
  bio_tools metadata <tool>

Examples:

• bio_tools install boltz
• bio_tools uninstall proteinmpnn
• bio_tools list-quick

Generic interfaces and code consolidation

This library provides an interface for input and output. This abstracts over the differences between tools, so applications can add many of them without repeating code. This library was built as the backbone of the Athanor Bio Tools web UI, and the external tool integrations in Molchanica. These use the Python and Rust libraries respectively. Bio Tools is designed to reduce repetition between these projects.

The CLI application is intended for cases where you're not writing software, but want to easily install these tools directly, without handling the system dependencies and python environments for each tool.

Installing tools

Handles installing applications. Details depend on the tool; some work by placing application executables in the appropriate places. Since many of these use Python, it uses uv to set up isolated environments.

The Rust installer replaces application-owned shell and PowerShell orchestration. The caller owns the outer directory; bio_tools owns the stable per-tool layout, downloads, environments, GPU selection, and verification.

InstallLayout::process_executables standardizes both consumers on assets under process_executables/ and environments under process_executables/python_envs/. InstallLayout::split remains available for custom roots. A progress callback can be attached with Installer::with_reporter for a GUI or structured setup log.

Rust:

use bio_tools::{install::Installer, tool_definitions::Tool};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut installer = Installer::for_process_executables("process_executables")?;
    installer.install(Tool::OpenDde)?;

    // Independent recipes continue after an upstream failure.
    let report = installer.install_many([Tool::Boltz2, Tool::ProteinMpnn]);
    for failure in &report.failed {
        eprintln!("{}: {}", failure.tool.name(), failure.error);
    }

    // Status: `status_quick` inspects markers, executables, and required assets
    // without launching the tool; `status_full` also runs its help/version probe.
    let status = installer.status_quick(Tool::OpenDde);
    println!("{:?}: {}", status.result, status.detail);

    let report = installer.uninstall(Tool::OpenDde)?;
    println!("Removed {} paths", report.removed.len());
    Ok(())
}

Python (equivalent):

from pathlib import Path
import bio_tools

root = Path("process_executables")
installer = bio_tools.Installer(root)
installer.install(bio_tools.Tool("opendde"))

# Independent recipes continue after an upstream failure.
for slug in ("boltz2", "proteinmpnn"):
    try:
        installer.install(bio_tools.Tool(slug))
    except RuntimeError as error:
        print(f"{slug}: {error}")

status = installer.status_quick(bio_tools.Tool("opendde"))
print(status.result, status.detail)

report = installer.uninstall(bio_tools.Tool("opendde"))
print(f"Removed {len(report.removed)} paths")

Running tools

run::CommandSpec describes a shell-free invocation independently of any one tool. CommandRunner builds a std::process::Command, overlays environment variables, writes optional stdin (or closes it when absent), drains bounded stdout and stderr concurrently, enforces a timeout, and either returns or rejects non-zero exits according to ExitPolicy.

Rust:

use std::time::Duration;

use bio_tools::run::{CommandSpec, RunLogSpec, run};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let command = CommandSpec::new("opendde")
        .args(["predict", "input.yaml"])
        .current_dir("work")
        .timeout(Duration::from_secs(600))
        .run_log(RunLogSpec::new("process_executables/run_logs", "opendde").artifact("."));

    let output = run(&command)?;
    println!("{}", output.stdout_lossy());
    Ok(())
}

Python (equivalent):

from pathlib import Path
import bio_tools

result = bio_tools.Command(
    ["opendde", "predict", "input.yaml"],
    cwd=Path("work"),
    timeout=600,
    run_log_dir=Path("process_executables/run_logs"),
    run_name="opendde",
).run()

print(result.stdout)
print(result.run_log_dir)

Installer::tool_command (Python: Installer.run) is the variant to reach for when the tool lives in a managed environment rather than on PATH; it resolves the installed console entry point for you.

Run logs

When a run log is configured, each invocation gets a unique directory below the given root and run name. run.log combines the exact argument vector, optional stdin, result, and complete stdout/stderr. The same streams are also available as stdout.txt and stderr.txt; inputs/ contains the pre-run artifact snapshot and outputs/ contains only files created or changed by the command. The in-memory output limit does not truncate these on-disk stream files.

Standalone CLI

The bio_tools executable wraps the same installer, status, and command-runner APIs for shell use:

bio_tools install opendde
bio_tools status-quick opendde
bio_tools status-full opendde
bio_tools metadata opendde
bio_tools run opendde -- --help

bio_tools list-quick
bio_tools list-full

bio_tools uninstall opendde

It uses $BIO_TOOLS_ROOT, or ./.bio_tools when unset; --root <directory> overrides both.

status-quick inspects installation markers, executables, and required assets without launching the tool. status-full also runs the tool's help/version probe and imports Torch or JAX where applicable to report its compute device. The corresponding list commands are list-quick and list-full; the older status and list commands remain aliases for the full variants. run resolves an installed console entry point inside that managed environment, so it does not require the tool on PATH. Tools that only expose a Python module or checkout script still need a tool-specific library invocation.

Example uses

• Building a GUI (Web or native) to these tools
• Setting up an API to programmatically interface.

Python bindings

The python/ package builds an ABI3 wheel with PyO3 and maturin, published to PyPI as athanor_bio_tools. It exposes the same process metadata, command runner, installer, and status probes; see the examples above, and the Rust docs for details on the underlying types.
