Dear Dr. Fornito, 
thank you for devloping this wonderful toolbox. 
so far, i've already performed the first level for all my subjects in SPM12, so i have a SPM.mat file for each subject. 
i also have my ROIs as .mat files  (created using MARSBAR). 
i ran into a technical question when trying to preform cPPI analyses on my data, hopes it's ok -
in the "cPPI_master.m" code lines 93-103 the user is expected to enter the ROI time courses.
i'm not sure how to extract these time courses at this point using SPM. 
when i run gPPI models using the gPPI toolbox this step is already implemented as a part of the PPPI.m function, so i'm not sure how to do this manually.
hope you can help me in this issue. 

many thanks,
Noa Magal.
