Documentation

These pages describe the ToMCAT dataset in detail — how the experiment was run, how the raw recordings are organized, and how the derived (synchronized) signals are produced. They are adapted from the ToMCAT data products document.

Dataset documentation

• Experiment protocol — the pre-session, the phases of the group session, and the modalities recorded for each participant.
• Raw data — the on-disk layout of the raw recordings: directory structure, per-file formats (REDCap, baseline tasks, XDF, audio, video, eye tracking), the testbed log files, and the physiological-data extraction step.
• Derived data products — the synchronized *_sync tables: the EEG/fNIRS channel montage, the filtering and 200 Hz master-clock synchronization pipeline, and a description of the deprecated (pre-2024-02-22) derived data products.

Schema & data

• Interactive schema diagram — the tables and the foreign-key relationships between them. Per-table and per-column descriptions also appear on each table's page.
• Message bus reference — field-level documentation for the JSON schemas in the minecraft_testbed_message.message column, organized by topic.
• Download the database — the full SQLite database and a compressed PostgreSQL dump, for whole-dataset work.

Related pages

• Papers and systems that use the dataset.
• Derived data releases and updates.
• Errata — known issues.
• Ethical review — consent and recruitment materials.
