Offline ExG Data Visualization with ExploreSignals

Explore Signals is a graphical tool for ExG data visualization and analysis. It supports importing data from Mentalab Explore devices from .csv and .bdf files, visualizing signals in time and frequency domains, applying common filters, applying ASR and exporting the processed data.

Key Features

• Load EEG/ExG data from .csv and .bdf files
• Apply standard EEG filters:
  • High-pass / Low-pass
  • Notch filter
  • Re-referencing
  • DC offset correction
• Multiple visualization modes:
  • Time-domain plot
  • FFT (Fast Fourier Transform) plot
  • Bandpower visualization (time series & bar chart)
  • Power Spectrum Density (PSD)
  • Spectrogram (time-frequency plot)
• Apply Artifact Subspace Reconstruction (ASR) to remove artifacts from EEG data
• Convert .csv data to .bdf and vice-versa
• Export processed data to .csv and .bdf
• Multi-file session support
• Export plots of processed data (FFT, bandpower etc.) as images
