Build Conditions for SPM12 first level model
spm12_condition( name, onset, duration, time_mod_order = 0, param_mod = NULL, orth = TRUE ) spm12_condition_list(cond)
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 |
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 |
orth | Orthogonalize the regressors within trial types. |
cond | List of conditions |
A list of objects, each with a name
, onset
,
duration
, and other condition values.
