Overview

Offline ExG data visualization with Explore Signals

Explore Signals is Mentalab’s desktop application for working with Explore recordings after a session.

You can load a recording, inspect it in the time and frequency domain, filter it, clean it with Artifact Subspace Reconstruction (ASR), and export the result. Explore Signals also converts between the formats used across an Explore workflow: binary .BIN files from the device memory, .csv, .bdf, .xdf, BIDS datasets, and EEGLAB datasets.

The current version is 0.4.0.

Key features

Area What you can do

Area	What you can do
Load	Open `.csv` and `.bdf` recordings, several at once. Import recordings from a BIDS dataset.
Filter	High-pass, low-pass, and notch filtering, average re-referencing, and DC offset correction.
Visualize	Time-domain plot, FFT, Power Spectrum Density (PSD), spectrogram, and bandpower over time or as bars.
Clean	Artifact Subspace Reconstruction with presets and a before-and-after comparison.
Export	Export the selected channels to `.csv` or `.bdf`. Save plots as images.
Convert	`.BIN` to `.csv`, `.bdf`, or BIDS. `.xdf` to BIDS. `.csv` to `.bdf`. `.csv`, `.bdf`, or `.edf` to EEGLAB `.set`.
Merge	Combine two recordings from Hypersync-synchronized devices, for example two 32-channel devices into one 64-channel recording.
Repair	Fill dropped packets in a `.csv` recording from Explore Desktop or explorepy using the `.BIN` file from the device.
