How Turbo-Satori works
Turbo‑Satori integrates into the real-time fNIRS workflow by connecting to an available data stream (or opening a simulated .sri, .hdr or .nirs project) and collecting an initial baseline window. During this baseline period the interface displays raw wavelength signals; once the baseline is established, real‑time conversion to HbO/HbR concentration begins and live plots switch to the haemodynamic signals. Preprocessing (detrending and low‑pass filtering) is applied per stream and can be tuned to balance smoothing versus latency. Channels are displayed in a selectable list, allowing you to choose which channels to include in the neurofeedback target. The selected channels are averaged together to produce a single feedback signal for oxy, deoxy, or a combined metric. This feedback value is visualized in a thermometer-style display and can be exported as numerical logs and PNG snapshots for later analysis.
Channel selection and scaling
Channels are displayed in a selectable list with color coding; multiple channels can be chosen for visualization and averaged for neurofeedback. A separate “Mask” column lets you hide noisy channels without affecting processing. Per‑channel scaling factors ensure plotted values remain within the display range (−1 to +1) and are saved to global settings for reuse.
Real‑time preprocessing and baseline handling
Raw and converted signals have independent preprocessing controls. Baselines for HbO/HbR are computed from the initial received samples (default: first 200 points) and can be adjusted in the Real‑Time Analysis Setup. Filtering is specified in Hz and internally mapped to the moving‑average length, avoiding excessive smoothing that would increase delay.

Export, snapshots and logging
By default Turbo‑Satori writes per‑timepoint numerical feedback values to a NeurofeedbackValues subfolder (files named Feedback-<timestamp>.txt) and can optionally save PNG snapshots of the feedback thermometer in NeurofeedbackImages. Each numerical export contains: pre‑condition oxy baseline, oxy feedback, oxy thermometer level, pre‑condition deoxy baseline, deoxy feedback, deoxy thermometer level, and current condition index. Toggle exports in the Neurofeedback dialog.
