ASA 7.5

ASA (Advanced Source Analysis) by ANT B.V. – Advanced Neuro Technology is a comprehensive software suite for EEG and MEG data analysis and source imaging. It streamlines the workflow from data import and preprocessing to head modeling, source reconstruction, visualization, and reporting. Designed for neuroscience research and advanced clinical workflows, ASA supports co-registration with individual MRI data and realistic head models to help localize and interpret underlying brain activity.

Key capabilities:

• Preprocessing and quality control: filtering, re-referencing, epoching, artifact detection, and reduction.
• Event-related and spectral analysis: ERP/ERF analysis, power spectra, and time–frequency exploration.
• Source reconstruction: equivalent current dipole modeling, distributed inverse solutions, and beamforming options.
• Head modeling and MRI integration: co-registration of sensor layouts with individual anatomy, spherical and realistic head models (including boundary element approaches), and tissue conductivity management.
• Visualization: interactive 2D scalp maps and 3D cortical/volume rendering, with time-locked and frequency-resolved displays.
• Connectivity and statistics: commonly used functional connectivity metrics and built-in statistical tools for group and condition comparisons.
• Compatibility and integration: works with ANT’s eego recordings and supports widely used EEG/MEG file formats; integrates with ANT hardware and the broader ANT ecosystem.
• Workflow efficiency: batch processing, templates, and configurable reports to support reproducible analyses.

ASA is typically deployed on Windows and is used by researchers and clinicians who need reliable, transparent pipelines for EEG/MEG preprocessing, source localization, and interpretation.
