TFT File Format Specification (.fff)

The .fff file format defines the structure of TriadicFrameworks resonance files.

These files describe:

• Resonant-time values (τ\_r)
• Triadic operators (D3, D6, D9)
• Frequency elevation (T\_f)
• Temperature coupling (ΛΘ)
• Composite constants (X = F3 \* T\_f)
• Optional metadata and comments

Structure#

A valid .fff file contains:

[TFT]
version = 1.3
tau\_r = <float>
D3 = <float>
D6 = <float>
D9 = <float>
Tf = <float>
LambdaTheta = <float>
F3 = <float>
 
Optional:
description = "Human readable notes"
tags = "comma,separated,keywords"

Example#

[TFT]
version = 1.3
tau\_r = 2.4
D3 = 3
D6 = 6
D9 = 9
Tf = 1.2
LambdaTheta = 0.8
F3 = 1.0
description = "Sample resonance file"

Purpose#

.fff files are used by:

• run\_tft.sh — execution
• validate\_tft.sh — structural checks
• convert\_tft.sh — readable summaries
• batch\_process.sh — multi-file workflows

They serve as the core data format for all TFT_3Pack examples.
