OptiNiSt

OptiNiSt creates scalable, extendable, and reproducible calcium imaging data analysis pipelines for optical neuroimage data analysis in neuroscience.

Key Features:

• Pipeline Creation: Researchers create analysis pipelines by selecting multiple processing modules and tuning their parameters.
• Algorithm Extensibility: New analysis algorithms can be added in addition to pre-installed tools.
• Reproducible Workflows: Entire workflows with modules and parameters are stored in a YAML file for reproducibility and deployment on high-performance computing clusters.
• Standard Data Format Output: Analysis results are stored in NWB (Neurodata Without Borders).
• Multi-format Image Input: Image data can be read in a variety of file formats.

Scientific Applications:

• Calcium Imaging Analysis: Streamlines analysis pipelines for image preprocessing, signal extraction, and subsequent neural activity analyses from optical neural recordings.
• Data Quality Assurance: Enables verification of data quality of original and processed data at each analysis step.
• Algorithm Optimization: Facilitates selection of optimal algorithms and parameters from numerous available options for calcium data processing.
• Standardized Data Sharing: Supports adoption of standard data formats for data sharing and meta-analyses in neuroscience.

Methodology:

OptiNiSt processes calcium imaging data through modular pipeline construction with parameter tuning, stores workflows as YAML configuration files, and outputs results to the NWB format.
