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).
