How to VisualizeRegressors

Hopefully this example piece of script should allow you to visualize your block or event regressors individually so as to check that everything is bein modelled the way it should be.

It's a SimpleThree step process:

1. Load your SPM design after having run your first level analysis

2. Save the regressor information within the SPM.mat file to another variable

3. Create a figure and plot your regressor of interest.

Example

1. Load SPM Design:
   a) Drag and drop the SPM.mat file into your command line.
   b) type: <load('/imaging/you01/yourfilesaddress/SPM.mat')>
2. Save the regressor information:
   in the command window, type: <desmat = SPM.xX.X>
3. Display your regressor:
   in the command window, type: <figure; plot(desmat(:,1))>
   * the 1 corresponds to the first regressor in your DM. To view the second
   regressor change this to a two and so on... Voila!
