Build Conditions for SPM12 first level model

Description

Build Conditions for SPM12 first level model

Usage

spm12_condition(
  name,
  onset,
  duration,
  time_mod_order = 0,
  param_mod = NULL,
  orth = TRUE
)

spm12_condition_list(cond)

Arguments

name	Name of the condition
onset	vector of onset of the condition
duration	vector of duration of the condition, must be the same length as onset
time_mod_order	time modulation order. This option allows for the characterization of linear or nonlinear time effects. Zero means no modulation
param_mod	parametric modulation. Not currently supported in spm12r
orth	Orthogonalize the regressors within trial types.
cond	List of conditions

Value

A list of objects, each with a name, onset, duration, and other condition values.

Examples

res = spm12_condition(
name = "condition1", 
onset = c(0, 2, 4, 6, 8),
duration = rep(1, 5) )
print(res)
L = list(
cond1 = list(onset = c(0, 2, 4, 6, 8), duration = rep(1, 5)), 
cond2 = list(onset = c(0, 2, 4, 6, 8) + 1, duration = rep(1, 5))
)
res = spm12_condition_list(L)
print(res)
