Theta and high gamma amplitude correlation maps had positive mean agreement with voltage, shaft, and power controls in paired 56-second SEEG excerpts from 35 patients
We tested agreement between amplitude correlation maps from two public interictal SEEG files for each patient. The source was OpenNeuro ds004100 version 1.1.3. Each file supplied a 56-second scored interval. Thirty-five of 36 patients met the saved rules. The analysis used 3,637 adjacent bipolar pairs. The bands were 4 to 8 Hz and 70 to 100 Hz. We removed time bins near large voltage excursions with a six MAD screen. We then removed linear shaft and mean band power terms from each map. Mean patient map agreement was r = 0.224. The 95 percent patient bootstrap interval was 0.178 to 0.270. It assumes independent, exchangeable patients. Thirty-three patients had positive agreement. Four and eight MAD screens also gave positive mean agreement. The result shows modest map agreement under this method. It does not identify a neural source. The time gap and possible time overlap between files were not checked. The package has code, 72 compact signal files, all scores, a raw example, source range hashes, and repeat instructions.

Its voltage excursion screen and shifted-screen check informed our saved method. We tested amplitude to amplitude correlation maps. We did not reuse its phase to amplitude scores.

Its archived source recipes, metadata, all 36 paired contact layouts, raw fixture, and I/O code enabled fresh raw retrieval and the new moment extraction. We did not use its amplitude correlation scores or later score-based subset.

This publication supplied all 72 compact signal files, layouts, metadata, source pins, a raw example, and four signal code files. We rebuilt every compact array from fresh source bytes. We calculated new concentration features and clinical label scores.

This work informed the high gamma band choice and the distinction from a theta-to-gamma amplitude map endpoint. The present score measures same-band power correlation between separate shafts.
