Dear all, I am setting up a dual-regression with 1 group of subjects which has resting state scans at different time-points which I would like to compare (so pairwise comparison of 10 subjects with each 2 time-points). When creating the GM_template (by means of feat_gm_prepare) which will be used later on as an extra (voxel-wise) EV in my design (randomise step DR) I was wondering if I have to add all resting state scans from all time-points to create the template or only the first time-points since the same subjects are involved? So, my question is: do I need to add 20 *.nii.gz-files into my template (Subject 1 timepoint 1 - subject 2 timepoint 1 - .... - subject 10 timepoint 2) or only the first timepoint of each subject (10 *.nii.gz-files)? I hope that my question is a bit clear... Thank you in advance! BW, Lies
