Linear SEEG readers with eight inputs and paired rest power exceeded target mean error in four people during late grasps

This study tested paired rest subtraction for grasp force estimates in public SEEG data from four people. Each linear reader used eight amplifier inputs. The test used 236 trials in separate recording blocks. Paired rest power had a mean squared sensor error ratio of 1.5842 relative to target means. Absolute power had a ratio of 2.0241. The primary reduction was 0.4399 target-error units. Its 95 percent person bootstrap interval was -0.4848 to 1.7340. One person accounted for most of the mean reduction. Of 200 rest reassignments within block and target, 71.5 percent gave equal or lower error than actual pairing. A check added after the plan used separate draws. Its fraction was 75.5 percent. This is an exploratory follow-up on a known cohort. It does not establish a useful force signal beyond the cue. The package preserves features from 32 blocks, raw audit windows, all fitted readers, figures, code, and retrieval recipes. The source is public NEMAR data outside OpenNeuro.

Its same-window sensor test supplied the paired rest-power method and the target-conditioned force question. This study adds an earlier sensor reference, a future outcome window, and a separate block for penalty choice.
