stimfunction: Generate a stimulus boxcar function.

In neuRosim: Simulate fMRI Data

Generate a stimulus boxcar function.

Description

Generates a stimulus boxcar vector for the specified time duration and microtime resolution based on the user-defined onsets and durations.

Usage

stimfunction(totaltime, onsets, durations, accuracy)

Arguments

totaltime	Total time of the design in seconds.
onsets	Vector representing the onsets of the stimulus in seconds.
durations	Vector representing the durations of the stimulus in seconds.
accuracy	Microtime resolution in seconds.

Details

If duration is a single number, it is assumed that all stimulus onsets have the same duration.

Value

A vector in microtime resolution specifying the stimulus boxcar function in 1-0 coding.
