In FEAT, go to Stats:Full model setup.
Basic shape: Custom (3 column format)
Filename: Find a text file which contains three columns of numbers.
Column 1 = onset time
Column 2 = duration
Column 3 = intensity
Here's a sample text file specifying the shape of the regressor:
5 1.20 1
10 0.65 1
15 0.74 1
20 0.97 1
25 0.52 1
etc.
Here a stimulus or cognitive process came on every 5 sec for variable
duration (e.g. RT) and the intensity of the stimulus per unit time was equal
(i.e. 1).
