Selection for distinct response patterns had an uncertain mean accuracy gain at four SEEG pairs in eight STReEF patients
We tested two fixed recording pair selection rules with public STReEF SEEG data from eight patients. Each patient had four conditions, five calibration pulses per condition, and five separate test pulses. The recorded stimulation contact order changed between groups. At four bipolar pairs, selection for distinct patterns gave 76.25% mean test accuracy. Selection for total separation gave 71.9%. The mean gain was 4.4 percentage points; the patient bootstrap interval was −1.9 to 11.9 points. The test did not establish a selection benefit. Matched before-pulse scores were 28.1% and 32.5%. The all-pair reference gave 77.5%. Four pairs required six to eight physical contacts. The split was per condition, not globally chronological. The package preserves all features, predictions, source checks, native examples, code, and figures. It supplies a narrow public test of response reading for stimulation feedback. It does not establish online performance or a neural mechanism.

We used its fixed STReEF metadata sample, source metadata, object version pins, byte range receipts, and MIT retrieval code. We selected its first four conditions per patient. We recovered the voltage again and computed new features, selection rules, and test results.

This version corrects a display rounding mismatch. It states the exact main score, 122/160 or 76.25 percent. The voltage features, selected pairs, predictions, and uncertainty estimates are unchanged.

- usesTwo calibration pulses gave lower mean four-condition accuracy than five at four SEEG pairs in eight STReEF patients after recorded contact order reversal
We reused its complete four-condition feature sample, test pulses, fixed reader and pair-selection rules, source receipts, and five-pulse result. The new analysis changes calibration input count and adds all early two-pulse subsets and component diagnostics. Independent checks reproduce its five-pulse counts exactly.
- usesSurviving contrasts raised mean 20–100 ms condition accuracy from 71.24% to 73.15% after known simulated contact loss in eight SEEG patients with unchanged surviving signals
This work supplied the fixed STReEF sample, calibration selector, features, source records, and retrieval code. All 32 selected layouts and 640 nominal decisions matched. The new test uses known simulated physical contact loss.
- usesFive templates per site certified 66.46% of SEEG search labels in eight patients on a ±9.77 ms grid under exact arithmetic
Used the metadata selection and pinned raw-range retrieval helpers through the immediate input publication. The fixed four-site sample and early/later split originate in this work. This is the same cohort, not an independent replication.
- usesSelection for one known contact loss gave lower mean minimum site accuracy in eight offline SEEG tests with four disjoint pairs at 20–100 ms
This work supplied the fixed four-site sample, all eight-patient features, the feature extractor, source checks, and MIT code. We kept the inputs, rebuilt all 320 public raw ranges, and reproduced its distinct-selection reader as an input check. The new comparison uses exact selection under an equal eight-contact budget and known contact omissions.
- usesOmitting lost inputs raised mean stimulation condition accuracy by 4.8 points in eight offline SEEG tests with known simulated contact loss
We reused its complete four-condition feature sample, five calibration and five test pulses per condition, fixed four-pair reader, source metadata, range receipts, and MIT retrieval code. We retrieved all 320 pinned epochs again and matched every array exactly. The fit, selected pairs, and intact decisions match its archive. We added known contact and shaft loss tests.
- usesAbsolute distance had no clear mean AUC gain over the label gap for absent conditions at four SEEG pairs in an offline test of eight patients
Uses the fixed four-condition sample, voltage features, source metadata, native byte examples, and retrieval code. These inputs permit a matched score comparison with no voltage from the absent condition in fitting or calibration.
- usesFive-pulse products raised mean log loss in eight SEEG patients versus geometric means after recorded contact order reversal
The four-pair selection rule comes from this earlier work. The present reader preserves its greedy log determinant rule and fits it with training pulses only.
- usesCalibrated Student t scores gave no observed mean loss gain in eight SEEG patients after contact order reversal with four recording pairs
We used its four-pair greedy log determinant rule, diagonal variance rule, eight cosine coefficients, and retrospective candidate-pair definitions. Each calibration fold refitted the pair rule without its held-out pulse.
