R parity of morie.entheo.data.load_dmt_imaging. Reads the
Carhart-Harris / Timmermann DMT-imaging dataset (20 subjects EEG +
parcellated fMRI; 15 motion-survived) from a local mirror. Falls
back to a reproducible synthetic record when the dataset is absent
or when R.matlab is not installed, so downstream code keeps
running in CI.
Usage
load_dmt_imaging(subject_id = NULL, root = NULL)
Arguments
- subject_id
integer or character (zero-padded 2-digit).
NULL means "all available subjects on disk".
- root
character. Override path to the DMT_Imaging mirror.
Defaults to $MORIE_DMT_IMAGING_ROOT, else a
DMT_Imaging folder in the per-user cache directory.
Value
Named list with components:
records list of subject records (eeg, fmri, behavioural).
root resolved dataset root path (or NA).
synthetic TRUE if any record is the fallback.
warnings character vector of advisories.
