construct a native AFNI hrf specification for '3dDeconvolve' and individually modulated events using the 'stim_times_IM' argument.

Usage

afni_trialwise(
  label,
  basis = c("spmg1", "block", "dmblock", "gamma", "wav"),
  onsets = NULL,
  durations = 0,
  subset = NULL,
  id = NULL,
  start = 0,
  stop = 22,
  precision = 0.3,
  summate = TRUE
)

Arguments

label: name of regressor
basis: Character string specifying the basis function type
onsets: Numeric vector of event onset times
durations: Numeric vector of event durations (default 0)
subset: Expression for subsetting events
id: Character string identifier for the term
start: start of hrf (for multiple basis hrfs)
stop: end of hrf (for multiple basis hrfs)
precision: Numeric precision for convolution (default 0.3)
summate: Logical whether to summate overlapping responses (default TRUE)

Value

an afni_trialwise_hrfspec instance

Examples


tw <- afni_trialwise("trialwise", basis="gamma", onsets=seq(1,100,by=5))
