Overview #
This document explains how clinicians can replace delayed Text Stats with real-time Event Trend Graphs inside BrainMaster 3.0.9. It provides step-by-step guidance for configuring event visibility, scaling, equations, colors, and screen layout to better visualize neurofeedback training activity.
Why Text Stats Are Not Real-Time #
The Text Stats panel updates roughly every 2 seconds, making it suitable for general observation but not rapid moment-to-moment feedback. Because of this delay, its values may temporarily mismatch the immediate training response.
Event Trend Graphs, however, reflect instant changes in training variables and align with both audio feedback and visual client screens.
Configuring Events for Display #
Enable and Set Event Visibility #
To show an Event on the Trend Graphs, it must be:
-
Enabled, and
-
Set to Visible in the Event Wizard.
Setting Trend Graph Scaling #
The Event Trend Graph section allows customization of:
-
Scale Factor (vertical amplitude)
-
Offset (baseline shift)
Examples include:
-
Scale 1 / Offset 0 for flag events (values 0–1)
-
Scale 10 / Offset –5 for z-scores ranging –5 to +5
This flexibility enables optimal visualization for frequency power, coherence metrics, or multi-component z-score ranges.
Using Event Equations #
Custom equations allow display of any component, such as:
-
Z-scores:
x=ZC012D(example variable) -
Percent time training condition is met:
x=E1P
All equations require clicking Check Equation to validate and save.
Color Customization #
Each Trend Graph line can be assigned a distinct color (e.g., yellow for z-scores, cyan for percent-time metrics) to improve readability during training.
Displaying Trend Graphs in the Training Screen #
Under the Display menu, turn off Text Stats and enable:
-
Trends (events) or
-
Wide Trends (events)
This provides full-screen, uncluttered trend visualization.
Example Multi-Component Training Layout #
A sample protocol demonstrates:
-
Event #1: Primary training equation
-
Event #5: Flash game trigger
-
Multiple Trend Graphs: individual z-score components
-
Final graph: percent-time metric (E1P)
The layout ensures no obstruction of key data even with animations active.
One limitation: coherence z-score displays may require screen scrolling.
Benefits of Using Event Trend Graphs #
-
Real-time alignment with training feedback
-
Clear visualization of multi-component protocols
-
Improved differentiation via custom scaling and color coding
-
More screen space for training displays without covering z-scores
