I am running a 1st level fMRI analysis using "specify 1st level". The experiment block design has been attached. The task lasts for 400 second (10 trials, each one 40 second). There are 200 scans and intersection interval is 2 second. After deletion of 5 volumes, two conditions have been defined as: (1) for blue screen (onset=[1 18 38 58 78 98 118 138 158 178] , duration=[5 8 8 8 8 8 8 8 8 8 8]) and (2) for white screen (onset=[8 28 48 68 88 108 128 148 168 188] , duration=16).
