SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PHENIX automates macromolecular structure determination workflows across X-ray crystallography, cryo-EM, and AlphaFold-assisted modeling.

Core Features & Use Cases

  • Map quality assessment (mtriage), map sharpening (auto_sharpen), density modification (resolve_cryo_em)
  • AlphaFold model processing and preparation for docking and refinement
  • Real-space refinement and validation workflows to improve map-model agreement

Quick Start

Install PHENIX from the official site, set up the environment, and run a basic workflow that performs map quality assessment and then real-space refinement on your model.

FAQPage Schema
How do I automate real-space refinement for cryo-EM models?

Real-space refinement for cryo-EM models is automated by this workflow to improve map-model agreement. It processes standard map and model formats through multi-step sequences, requiring a PHENIX installation to run.

What is the best way to assess cryo-EM map quality and apply sharpening?

Cryo-EM map quality assessment and sharpening are handled through automated pipelines that perform mtriage and auto_sharpen. This evaluates map characteristics and applies density modification using resolve_cryo_em.

Can I use AlphaFold models for docking and refinement in cryo-EM pipelines?

AlphaFold models can be processed and prepared for docking and real-space refinement within cryo-EM pipelines. The workflow accepts standard model formats and integrates AlphaFold processing into the structure determination sequence.

Do I need a local PHENIX installation to run macromolecular structure determination workflows?

A local PHENIX installation is required to run these macromolecular structure determination workflows. The environment must be set up properly to execute map analysis, model docking, and refinement tasks with parallel processing options.

Does this workflow support parallel processing for multi-step structure determination?

Parallel processing is supported for multi-step structure determination sequences. This allows efficient execution of complex pipelines covering map quality assessment, model docking, and real-space refinement across X-ray crystallography and cryo-EM data.
