This dataset accompanies the following paper: Hamilton, Chang, Lee, and Chang. Semi-automated anatomical labeling and inter-subject warping of high-density intracranial recording electrodes in electrocorticography This data includes an anonymized and de-identified CT and T1 MRI scan, plus all intermediate and final files produced by the img_pipe software for testing and instructional purposes. This subject had a right hemisphere implantation including high density grids, strip electrodes, and depth electrodes. img_pipe software and installation instructions can be found at http://github.com/changlabucsf/img_pipe If you wish to follow along yourself, we recommend creating a new subject in your Freesurfer $SUBJECTS_DIR, then copy the acpc and CT directories from this dataset into that new subject directory. The electrode montage is provided in test_subj_montage.txt and describes the type of electrodes implanted (grid, strip, or depth) and their general location.
