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
)

Arguments

label	name of regressor
basis	the impulse response function or the name of a pre-supplied function, one of: "gamma", "spmg1", "spmg2", "spmg3", "bspline", "gaussian".
onsets	optional onsets override. If missing, onsets will be taken from the event_model
durations	optional durations override. If missing, onsets will be taken from the event_model
subset	an expression indicating the subset of 'onsets' to keep
id	a unique character identifier used to refer to term, otherwise will be determined from variable names.
start	start of hrf (for multiple basis hrfs)
stop	end of hrf (for multiple basis hrfs)

Value

an afni_trialwise_hrfspec instance

Examples

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