Calibration on matching codes lowered mean later fNIRS error in 12 adults with three-second windows and one nearer channel

We tested transfer between six recorded event codes in 12 adults from OpenNeuro ds007420, version 1.0.5. Each model used one nearer channel and an intercept. Two early events trained each code fit. Two later events tested all six fits. With three-second windows and equal training counts, matching codes gave 29.64% lower geometric residual error than the other five codes. The 95% adult-bootstrap interval was 26.14% to 32.76%. All 12 adult mean scores favored matching codes. Planned checks kept this direction. The package preserves compact signal data, all code transfer errors, source identities, code, figures, and raw retrieval instructions. Full raw extraction and a separate numerical implementation passed. The source duration fields conflict, but their event onsets agree. The common event order limits interpretation. Lower optical error does not show preservation of brain signals. Related studies use the same cohort.

    This related report compares separate code fits with a pooled fit and gives a code transfer table. It helps define the distinct scope of our equal-count single-code transfer test. Both reports use the same cohort and do not provide independent biological replications.

    This study uses the stored motion differences, channel pairs, event tables, and source identities from this publication. Full raw files verified the reused arrays. The new test compares matching and other single-code fits with equal training counts in the same cohort.
