OpenHCS

Turn high-content microscopy images into reproducible measurements
One reviewable workflow across the GUI, Python, CellProfiler, and local agents

OpenHCS is designed for imaging scientists and research software teams running high-content studies where many wells, sites, channels, Z planes, or time points must be analysed consistently. Source selection, processing steps, and result definitions stay together in one validated pipeline instead of being split across interface-only state, scripts, and automation.

It is a good fit when a workflow must remain reviewable across visual editing, code, and automation. The same pipeline can be edited in the desktop GUI or as Python, imported from supported CellProfiler .cppipe files, and built or reviewed through the local MCP surface.

Install

Windows installer · macOS installer · Installation options

The graphical installers set up an isolated CPU-safe desktop environment with the OpenHCS GUI, CellProfiler compatibility, local MCP server, Napari, Fiji/ImageJ, and Bio-Formats. GPU libraries remain optional.

See OpenHCS in use

Browse the UI and viewer gallery · Watch an agent build, debug, run, and inspect a workflow

OpenHCS processes large microscopy datasets with a compile-then-execute architecture. Pipelines are validated across the selected execution axes before processing starts, preventing late failures after expensive work. Design pipelines in the GUI, export to Python, edit as code, and re-import — switching between visual and programmatic workflows. The local MCP exposes that same workflow model to supported agents, so agent-authored pipelines remain visible, editable, and reviewable in the GUI and generated Python.

⚡ Key Capabilities

🛡️ Compile-Time Validation

Configuration is resolved once into step snapshots and a compilation session. Typed plans then validate sources, artifacts, materialization, memory contracts, and worker requirements before execution begins. Errors surface immediately, not after hours of processing.

🔄 Bidirectional GUI ↔ Code

Design pipelines visually, export as executable Python, edit in your IDE, re-import to the GUI. Code generation works at any scope level — function patterns, individual steps, pipeline configs, full orchestrator scripts — any window holding objects can generate and re-import code.

🧠 Agent-Assisted Workflows

Give a supported MCP client a microscopy folder or plate and an analysis goal. It can inspect the connected execution server's functions, build and validate a typed pipeline, run it, inspect results in OpenHCS or a viewer, and revise the generated Python. A built-in code assistant can also use local Ollama or configured remote LLM endpoints.

⚡ Full Multiprocessing & Multi-GPU

Bounded worker lanes use ProcessPoolExecutor by default, with deterministic well assignment and sequential processing inside each lane. A GPU scheduler assigns devices to workers; single-worker and debugging configurations can use inline or threaded execution.

🔌 Any Python Function

Register any Python function by decorating it with @numpy, @cupy, @pyclesperanto, @torch, or another memory-type decorator. Custom functions receive contract validation, UI integration, multiprocessing-safe import identity, and the same server-owned catalog projection as built-in functions. Persisted functions live in the platform-specific OpenHCS user-data directory.

📊 Results Materialization

Callable and module artifact contracts declare semantic outputs independently of Python argument names. The artifact graph and materialization plans route images, measurements, object labels, relationships, tables, and files to their configured stores and exporters.

🔬 Process-Isolated Napari & Fiji

Stream images to Napari and Fiji/ImageJ in real time during pipeline execution. OpenHCS StreamingConfig declarations and viewer adapters own identity, display, and persistence policy. PolyStore builds generic storage and streaming payloads; ZMQRuntime supplies process-isolated transport, readiness, acknowledgments, and lifecycle.

🪟 Live Cross-Window Updates

Edit a value in GlobalPipelineConfig — watch it propagate in real-time to PipelineConfig and StepConfig windows. Dual-axis resolution (context hierarchy × class MRO) with scope isolation per orchestrator.

🧬 CellProfiler Pipeline Import

Open .cppipe files in the desktop application or lower them from Python into ordinary PipelineConfig and FunctionStep declarations. Named images, objects, measurements, relationships, and exports use the same typed compiler and runtime as native OpenHCS pipelines. The source-backed Official30 suite continuously exercises 30 pipelines from CellProfiler examples, tutorials, and benchmark supplements under explicit equivalence policies.

🤖 MCP Agent Automation

Use the local stdio MCP server with ChatGPT desktop, Codex, Claude Desktop, and other supported clients, or deploy the separately secured HTTP surface. The graphical installers register detected local clients automatically. Capability profiles, schemas, knowledge, UI attachment, authoring, execution, runtime inspection, viewer review, and governed custom-function registration are projected from typed authorities rather than duplicated tool lists.

🧩 The OpenHCS Ecosystem

OpenHCS is built on 8 purpose-extracted, separately published libraries — each solving a general problem and all composed into one platform:

Library	Role in OpenHCS	What It Does
ObjectState	Configuration framework	Lazy dataclasses with dual-axis inheritance (context hierarchy × class MRO) and `contextvars`-based resolution
ArrayBridge	Memory type conversion	Unified API across NumPy, CuPy, PyTorch, JAX, TensorFlow, pyclesperanto with DLPack zero-copy transfers
PolyStore	Unified I/O & stream payloads	Generic storage and streaming payload primitives, backend lifecycle, virtual workspaces, atomic writes, format detection, and ROI extraction
ZMQRuntime	Process & transport runtime	Generic request, status, progress, cancellation, process-lifecycle, and viewer-control transport protocols
PyQT-reactive	UI form generation	React-style reactive forms from dataclasses with cross-window sync and flash animations
pycodify	Code ↔ object conversion	Python source as serialization format — type-preserving, diffable, editable, with collision handling
python-introspect	Signature analysis	Pure-Python function/dataclass introspection for automatic UI generation and contract analysis
metaclass-registry	Plugin discovery	Zero-boilerplate registry system powering microscope handler and storage backend auto-discovery

🔬 Microscope & Function Support

Image Sources

Source	Support
ImageXpress	Native plate and metadata handling
Opera Phenix	Native plate and metadata handling
Bio-Formats	Arbitrary folders and supported microscopy containers
OMERO	Remote image and metadata access
OpenHCS format	Native generated and materialized plates

Source handlers are auto-detected and extensible through metaclass-registry.

Functions — Automatic Discovery

Library or route	Execution memory
scikit-image and OpenHCS native	NumPy / CPU
pyclesperanto	OpenCL GPU
CuPy and cuCIM	CUDA GPU
PyTorch, JAX, and TensorFlow functions	Declared CPU/GPU arrays
User custom functions	Declared by their memory-type decorator

The connected execution server owns the available catalog, so remote GPU and custom-function availability is reflected without a manually maintained list. ArrayBridge provides compatible memory conversion, including zero-copy paths where supported.

Processing domains: image preprocessing · segmentation · cell counting · stitching (MIST + Ashlar GPU) · neurite tracing · morphology · measurements

🚀 Quick Start

For most desktop users, download the Windows installer or macOS installer. Neither download requires ZIP extraction or an existing Python installation.

For a manual installation, create a virtual environment and install the same CPU-safe desktop surface as the graphical installers:

bash

# Complete CPU-safe desktop environment
python -m pip install "openhcs[gui,viz,bioformats,mcp,cellprofiler-compat]"

# Launch the application
openhcs

# Launch the local MCP server over stdio
openhcs-mcp

Smaller environments can select only the required features:

bash

# Basic installation with GUI
python -m pip install "openhcs[gui]"

# Add Napari viewer
python -m pip install "openhcs[gui,napari]"

# Add Fiji/ImageJ viewer
python -m pip install "openhcs[gui,fiji]"

# Add both viewers
python -m pip install "openhcs[gui,viz]"

# Add GPU acceleration on a compatible CUDA 12 system
python -m pip install "openhcs[gui,gpu]"

# Full installation (GUI + viewers + GPU)
python -m pip install "openhcs[gui,viz,gpu]"

# Add the local MCP server for agent clients
python -m pip install "openhcs[gui,mcp,viz]"

server.ts

# Or lower a CellProfiler pipeline into public OpenHCS declarations
from pathlib import Path

from objectstate import ensure_global_config_context
from openhcs.core.config import GlobalPipelineConfig
from openhcs.core.orchestrator.orchestrator import PipelineOrchestrator
from openhcs.interop.cellprofiler.pipeline_import import import_cellprofiler_pipeline

plate_path = Path("/data/plate").resolve()
ensure_global_config_context(GlobalPipelineConfig, GlobalPipelineConfig())
steps, pipeline_config = import_cellprofiler_pipeline(
    "analysis.cppipe",
    source_root=plate_path,
)

orchestrator = PipelineOrchestrator(
    plate_path,
    pipeline_config=pipeline_config,
).initialize()
compilation = orchestrator.compile_pipelines(steps)
execution_bundle = compilation["execution_bundle"]

The GUI and execution services consume the same list[FunctionStep], PipelineConfig, and typed execution bundle. See the API orientation for the explicit low-level execution call and progress lifecycle.

📦 All installation options

bash

python -m pip install "openhcs"              # Headless engine
python -m pip install "openhcs[gui]"         # Desktop GUI
python -m pip install "openhcs[gui,napari]"  # GUI + Napari viewer
python -m pip install "openhcs[gui,viz]"     # GUI + Napari + Fiji
python -m pip install "openhcs[gui,viz,gpu]" # Full installation
python -m pip install "openhcs[gpu]"         # Headless + GPU
python -m pip install "openhcs[omero]"       # OMERO integration
python -m pip install -e ".[all,dev]"         # Development (all features)

The gpu extra requires a compatible CUDA 12 environment on a supported NVIDIA platform. For a CPU-only desktop installation, install openhcs[gui] without the gpu extra.

🗄️ OMERO integration

OMERO requires zeroc-ice, whose compatible wheels are not published through the normal project metadata. Install the helper requirements before the extra:

bash

python scripts/install_omero_deps.py
pip install 'openhcs[omero]'

Equivalent requirements-file installation:

Terminal

pip install -r requirements-omero.txt
pip install 'openhcs[omero]'

Supported on Python 3.11 and 3.12. See Glencoe Software for manual installation.

⚙️ Architecture Highlights

Resolved, typed pipeline compilation — catch errors before execution starts

Code

PipelineConfig + list[FunctionStep]
        ↓ resolve once
StepSnapshot + CompilationSession
        ↓ derive and validate
typed CompiledStepPlan objects
        ↓ package
CompiledExecutionBundle
        ↓ execute
runtime values + materialized artifacts

The authoring surface remains an ordered linear step list. ObjectState inheritance keeps defaulted configuration sparse, while compilation derives and exposes the exact source and artifact dependencies required for execution; the derived dependency graph is not a second workflow the user must author.

Pipelines are compiled for every selected execution axis before processing begins. Runtime workers consume the compiled bundle rather than reinterpreting mutable declaration objects. Read more →

Dual-Axis Configuration — context hierarchy × class MRO

Resolution walks two axes simultaneously: the context stack (Global → Pipeline → Step) and the class MRO (inheritance chain). Built on contextvars for thread-safe, scope-isolated resolution. Preserves None vs concrete value distinction for proper field-level inheritance. Powered by ObjectState. Read more →

Bidirectional GUI ↔ Code — code generation at any scope level

Any window holding ObjectState objects can generate and re-import executable Python:

Code

Function patterns · Individual steps · Pipeline configs · Full orchestrator scripts
              ↕  generate / AST-parse back  ↕

Each scope encapsulates all lower-scope imports. Generated code is fully executable without additional setup. Edit in your IDE or external editor, save, and the GUI re-imports via AST parsing. Powered by pycodify + python-introspect. Read more →

Cross-Window Live Updates — class-level registry + Qt signals

A class-level registry tracks all active form managers. When a value changes in any config window, Qt signals propagate the change to every affected window with debounced, scope-isolated refreshes. Global → Pipeline → Step cascading with per-orchestrator isolation. Powered by PyQT-reactive. Read more →

More patterns — storage, viewer integration, function discovery, memory types

Storage and viewer streaming: PolyStore owns generic storage and streaming payload primitives; ZMQRuntime owns process, transport, readiness, acknowledgment, and lifecycle protocols; OpenHCS StreamingConfig declarations plus the Napari/Fiji adapters own viewer identity, display, and application policy.
Automatic Function Discovery: registry-discovered functions with contract analysis and type-safe integration via python-introspect + metaclass-registry
Memory Type Management: Compile-time validation of array type compatibility with zero-copy conversion via ArrayBridge
Custom Function Registration: Any Python function decorated with @numpy, @cupy, @pyclesperanto, etc. is auto-integrated with contracts, UI forms, and the function registry
Evolution-Proof UI: Type-based form generation from Python annotations — adapts automatically when signatures change
