Dear Christina,

You can enter the beta images, but then your design should not be the 
SPM.mat. Instead, you have to enter the design manually (specify design, 
manual). The number of conditions then corresponds to the number of beta 
images that you select.

Example:

cond1 onset: 0 duration: 1
cond2 onset: 1 duration: 1

with the conditions corresponding to the beta images you enter (you need 
to keep the same order for the conditions as you selected the files).

The SPM.mat can be used with the time-series only.

I hope this helps.

Thank you for your interest in PRoNTo.
All the best,
Jessica

> Hello,
> Thanks for making this toolbox!  I have a pretty basic question so I apologize if it's already answered elsewhere.  In the manual under 2.2.4, it says that for rapid event-related design experiments, the best approach is to input the beta images obtained by first running a GLM analysis on the original data.  Since my experiment used a rapid event-related design, I inputted the 'beta_00*' images as well as the 'SPM.mat' file created from the GLM analyses for each participant.  All of that went through fine.  However, when I review the data and design, all of the scans are getting discarded.  There was another thread on forum that said that this happens if my events are located further in the time-series than the number of images I provided.  Since I'm inputting beta images from the GLM analysis, I'm inputting relatively few images.  Am I inputting the correct images?  Also, for event-related designs, should the HRF delay and overlap corrections be 0?
