Arguments

subject: 'RAVE' subject
electrodes: string or integers indicating electrodes to load
reference_name: name of the reference table
epoch_name: name of the epoch trial table
time_windows: numeric vector with even lengths, the time start and end of the trials, for example, c(-1, 2) means load 1 second before the trial onset and 2 seconds after trial onset
stitch_events: events where the time_windows is based; default is trial onset (NULL)
...: passed to RAVESubjectBaseRepository constructor
quiet: see field quiet
repository_id: see field repository_id
strict: whether to check existence of subject before loading data; default is true

Value

A RAVESubjectEpochRepository instance

Examples


if( has_rave_subject("demo/DemoSubject") ) {


repository <- prepare_subject_with_epochs(
  "demo/DemoSubject", electrodes = 14:16,
  reference_name = "default", epoch_name = "auditory_onset",
  time_windows = c(-1, 2))

print(repository)

head(repository$epoch$table)

electrodes <- repository$electrode_instances

# Channel 14
e <- electrodes$e_14

# referenced voltage
voltage <- e$load_data_with_epochs("voltage")

# 6001 time points (2000 sample rate)
# 287 trials
# 1 channel
