This is a collection of preprocessed data and standalone Matlab analysis code for the PLoS: Biology article of the same name, https://doi.org/10.1371/journal.pbio.3001575. The primary processed diffusion MRI connectivity data was reported and previous distributed in our eNeuro article https://doi.org/10.1523/ENEURO.0416-20.2020. The replication dataset was reported and previous distributed by Arnatkeviciute et al. 2021, Nature Communications (https://doi.org/10.1038/s41467-021-24306-2). Please cite these publications when using relevant code or data. Files with the .mat extension are Matlab v7.3 data files. The raw imaging data from which these files were derived are available from https://db.humanconnectome.org.
