Delay compensation reduced mean simulated pulse phase error in seven SEEG rest recordings with an assumed 50 ms delay
We tested phase timing at simulated pulse arrivals in public SEEG rest data. We used four selected pairs from each of seven people in OpenNeuro ds006065, version 1.0.0. At a 50 ms arrival delay, a fixed phase advance reduced mean target error from 99.60 to 69.85 degrees. All seven participant means improved. The mean decrease was 29.74 degrees. The descriptive 95% participant interval was 23.38 to 36.05 degrees. An early amplitude gate reduced corrected error to 52.92 degrees and reduced the trigger rate from 1.70 to 0.80 per second per pair. Without the phase advance, the gate increased error from 99.60 to 111.53 degrees despite a narrower phase distribution. The fixed correction increased error at evaluated delays of 0 and 100 ms. No stimulation was delivered. The reference uses future voltage and is not biological ground truth. This exploratory study reuses seven clinical recordings. The package preserves selected signals, a causal replay tool, all pulse events, three figures, code, source hashes, and reproduction instructions. Full source extraction and an independent repeat passed.

Its early amplitude gate result motivated our secondary gate comparison at accepted pulse arrivals. We did not use its code or reported outcomes as test data. Our fixed threshold came from the parent estimator and early calibration.

This publication supplied the selected bipolar voltage signals, source provenance, selection rules, and weighted sinusoid fit and offline reference functions. We preserved these inputs and checked the complete source files and extraction. We added causal pulse schedules and evaluated simulated arrival phases. The seven participants are reused.

We use the wrapped positive phase crossing and minimum pulse interval rule from the sinusoid replay. We add learned crossings and fit a sinusoid offset for the 50 ms delay.
