Additions

  • New Blender Tool for Full Blend File Creation: Complete Blender integration with automated blend file generation, electrode positioning, and visualization setup. Streamlined workflow for creating publication-ready 3D visualizations directly from simulation results.
  • Ex-search: Added an option to run the a truly exhaustive search option as all selected electrodes are pooled together instead of placed in stationary buckets. Refer to ex-search wiki tab for more information.
  • New Correlation Mode for Cluster-Based Permutation Testing: Enhanced statistical analysis capabilities with correlation-based cluster permutation testing, providing more robust statistical inference for connectivity and relationship analyses.
  • Unified Command-Line Experience: All CLI tools now support both interactive mode (run without arguments) and direct mode (with flags). Consistent colored output, clear prompts, and intelligent option discovery across all commands.
  • Multi-Processing Simulator: Parallel processing capabilities for faster simulation runs, optimized resource utilization, and scalable performance across different hardware configurations.
  • Enhanced Testing Suite Coverage: Comprehensive test coverage expansion including simulator workflows, statistical analysis pipelines, and integration testing for improved reliability and stability.
  • Improved Security CI/CD Pipeline: Strengthened GitHub Actions workflows with enhanced security scanning, automated vulnerability detection, and improved code quality gates throughout the development pipeline.
  • Refactored pre-processing tools: Removed all bash scripts to improved maintainability and reduce complexity. Updated all relevant benchmarks, tests, and docs.

Fixes

  • Experimental Movea Tool: Temporarily removed the experimental movea tool to focus development efforts on core functionality and stability.
  • Bug Fixes & Reliability: Fixed GUI crashes and timeout issues. Improved path handling and import reliability. Updated electrode templates for better compatibility. Enhanced security scanning and CI/CD workflows.
  • Documentation Updates: New CLI and GUI documentation pages. Improved Blender integration instructions. Added visualizer documentation. Better organization of documentation images.
