Dear SPMers,
I am hoping that someone can help me. I have recently been using the
spm_fMRI_design.m script written by Jesper Andersson in order to ensure
than my hrf and temporal derivative terms are orthogonal. I have used
the ‘Review Design’ utility in SPM to check the orthogonality however, what
I want to do is extract the actual values of the hrf and temporal
derivative at each data point from the SPM.mat file to enable me to
manually check the orthogonality and normality of my data. However, I
cannot seem to find where these values are stored within the SPM.mat file
to enable me to do this.
I would be grateful for any help.
