Data

This folder contains all the data that serves as input for the analysis scripts. ABCD data cannot be shared on open repositories.

Full reproduction. In order to fully reproduce the analysis described in the manuscript, the interested reader needs to have their own personal access to the ABCD data repository. After obtaining access, the required data files can be placed in the data folder (see how to reproduce this repository for more information).

Computational reproduction. To facilitate computational reproducibility, we provide synthetic data files. These files contain simulated data with the same variables as the original data and with the same basic characteristics. They are generated in the generate_synthetic_data.R script and can be used as input to the data analysis functions. The synthetic versions of files can be recognized by the “_synth” suffix. Note that, because the values are not identical to the real data, the output will deviate from the statistics described in the manuscript. The synthetic data files resemble the data after preprocessing (as done in /scripts/1_data_prep). Therefore, when using the synthetic data you should skip the preprocessing steps and continue to the analysis scripts (/scripts/2_analyses).
