Plot ERP Measurement GUI

This demo shows how to use the interactive ERP measurement GUI for visual exploration and parameter tuning.

What Does It Do?

plot_erp_measurement_gui opens an interactive window that lets you explore ERP measurements in real time. You can adjust the analysis interval, baseline window, measurement type, and channel — all with live visual feedback. This is useful for:

• Teaching — demonstrating how measurement choices affect results

• Parameter exploration — finding the right analysis window before batch processing

• Visual validation — confirming that automated measurements are sensible

Relationship to erp_measurements

Use the GUI to explore and decide on your measurement parameters, then apply those parameters programmatically with EegFun.erp_measurements() for your final analysis.

Workflow Summary

This demo covers:

Basic Usage

• Launch the GUI with all conditions overlaid

Single Condition

• Explore one condition at a time

Pre-configured Settings

• Open the GUI with specific initial channel, measurement type, and intervals

Code Examples

# Demo: Interactive ERP Measurement GUI
# Explore ERP measurements interactively with live visual feedback.
# Useful for teaching, parameter exploration, and visual validation
# before batch processing with erp_measurements().

using EegFun
# Note: EegFun.example_path() resolves bundled example data paths.
# When using your own data, simply pass the file path directly, e.g.:
# dat = EegFun.read_raw_data("/path/to/your/data.bdf")

dat = EegFun.read_data(EegFun.example_path("data/julia/erps/example1_erps_good.jld2"))

# All conditions overlaid
# EegFun.plot_erp_measurement_gui(dat)
# 
# # Single condition
# EegFun.plot_erp_measurement_gui(dat[1])

# Select some specific initial settings
EegFun.plot_erp_measurement_gui(
    dat[1],
    channel = :Cz,
    analysis_type = "mean_amplitude",
    analysis_interval = (0.3, 0.5),
    baseline_interval = (-0.2, 0.0),
)
