Files & session data

Files in the launch folder#

An invalid or missing configuration file is replaced by defaults at launch.

Session folder#

sessions/
└── session-1791404921802059900/
    ├── index.sqlite        # timestamps, metadata, events, devices, capability matrix
    ├── index.sqlite-wal    # write-ahead log while the session is open
    └── streams.bin         # raw audio, camera frames, telemetry, RF payloads

The folder name is session- followed by the creation time in Unix nanoseconds.

What is inside#

• Frames — every sample block or reading, with the session-clock time, sequence, rate, values and full provenance (source, device, units, classification, algorithm, interface, simulated flag).
• Events — session start and end (with drop counts), trial plans and host markers, notes, pause/resume, device status, input events, haptic commands, serial traffic, BLE advertisers, RF progress and budget events.
• Metadata — the configuration used, hardware descriptors, the capability matrix at creation, loopback latency when calibrated, the Synthesis expected sources and the final status.
• RF records — rf.spectrum (PSD per window), rf.features (17 features) and rf.iq (lossless 8-bit IQ), each carrying the window's timing and front-end read-backs.
• Synthesis records — derived.synthesis, one per epoch, with the feature manifest, missingness, lineage and relationships.

Open sessions in NOESISReader#

Point NOESISReader at the session-<id> folder. It opens the session read-only and keeps its own work in a separate session-<id>.noesisreader project file beside the folder. See Sessions & project files.
