afni_trialwise: construct a native AFNI hrf specification for '3dDeconvolve'...

In bbuchsbaum/fmrireg: R package for the anlysis of fmri data

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

Description

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))
