simprepTemporal {neuRosim} | R Documentation |
Prepare temporal structure of the data
Description
Prepare a list defining the necessary parameters to specify the temporal structure of the activation data.
Usage
simprepTemporal(totaltime, regions = NULL, onsets, durations,
TR, effectsize, accuracy=0.1,
hrf = c("gamma", "double-gamma", "Balloon"),
param = NULL)
Arguments
totaltime |
Duration of the experiment. |
regions |
Number of regions. If not specified, it is assumed that all regions have the same design matrix. |
onsets |
List or vector representing the onsets of the stimulus in seconds. |
durations |
List or vector representing the durations of the stimulus in seconds. |
TR |
Repetition time in seconds. |
effectsize |
List or number representing the effectsize in each condition. |
accuracy |
Microtime resolution in seconds. |
hrf |
Haemodynamic response function (double-gamma is default) |
param |
Vector, matrix or array representing the parameters of the haemodynamic response function. |
Value
A list with the necessary arguments to be used in simVOLfmri
or simTSfmri
.
