XIPP

XIPP analyzes multidimensional Nuclear Magnetic Resonance (NMR) data for proteins, DNA, RNA, and protein–nucleic acid complexes to support backbone and sidechain assignment, NOE assignment, and relaxation-series analyses.

Key Features:

• Multidimensional NMR Data Analysis: Handles multidimensional NMR datasets for labeled biomolecules including proteins, DNA, and RNA.
• Java and Jython Implementation: Implemented in Java with Jython scripting for extensibility and customization.
• Study-Oriented Organization: Organizes analyses into predefined study types such as backbone assignment, sidechain assignment, NOE assignment, and relaxation-series experiments.
• Extensibility via Jython Scripts: Default study types are defined by Jython scripts that can be modified to create custom study configurations.
• Overlay and Comparison of Experiments: Allows simultaneous viewing and overlaying of multiple NMR experiments for comparative analysis.
• Backbone Assignment Support: Includes built-in functionalities specifically to assist with backbone assignment workflows.

Scientific Applications:

• Protein Structure Determination: Supports backbone and sidechain assignment workflows used in determining three-dimensional protein structures.
• Nucleic Acid Research: Applicable to NMR studies of DNA and RNA and their interactions with proteins.
• Protein–Nucleic Acid Complex Analysis: Enables analysis of structural dynamics and interactions in protein–nucleic acid complexes using NOE and relaxation-series data.

Methodology:

Implemented in Java with study types defined by Jython scripts; supports simultaneous overlaying of multiple NMR experiments and provides routines for backbone and sidechain assignment, NOE assignment, and relaxation-series analyses.
