Region columns are sorted alphabetically. Cells for which no data is available are set to NA.
agg.res.long.to.wide(agg_all_subjects, subjects_list, agg_fun = NULL)dataframe in wide format, with one row per subject. The first column is named 'subject' and holds the subject identifiers, the remaining columns are named after the atlas regions and hold the aggregated values.
