Ot2Rec

Ot2Rec enables scientists to build custom, automated processing workflows for cryo-electron tomographic image reconstruction using a plugin-based architecture with a unified application programming interface structure.

Key Features:

• Plugin-based workflow construction: Users build custom pipelines using plugins that follow a unified application programming interface structure, allowing mix-and-match of plugins and extensibility through custom plugin development.
• Semi-automatic processing: The workflow automates image processing from individual micrographs to full tomograms, providing speedup over manual processing.
• Metadata aggregation and reporting: Built-in reporting aggregates metadata from all processes run and outputs them in Jupyter Notebook and/or HTML formats for quick review of image processing quality.

Scientific Applications:

• 3D structure determination of proteins and macromolecules: Electron cryo-tomography probes 3D structures at the nanometer scale for studying complex structures of proteins and other macromolecules in the biomedical field.
• High-throughput tomographic data processing: Addresses the challenge of processing terabyte-scale daily data output from modern microscopes where manual processing speed cannot keep up with instrument throughput.

Methodology:

Ot2Rec implements a pipelining approach with plugins as basic building blocks following a unified application programming interface structure; specific computational methods depend on the individual plugins selected by the user for their custom workflow.
