The materials and methods for each section of the main text are available in the section with same heading in the supplementary materials (21); i.e., supplementary content for a given main text section within the supplementary materials is named in a parallel fashion. Detailed data protocols are available in the supplementary materials. Moreover, associated and derived data files are available at the PsychENCODE resource site (19). Often we provide multiple versions of the derived summary files with different parameterizations (e.g., for the single-cell profiles and for eQTLs).
