Hi, I am running a retinotopy analysis using fsfast 5.3. The design has 15 TR blank before and after wedge presented for 30 TR with 7 repeats, and ring presented for 24 TR with 7 repeats. Here is my analysis: mkanalysis -s vz -a rtoy.self.rh -fsd bold -fwhm 2 -nskip 15 -TR 1.5 -retinotopy 48 -paradigm rtopy.par. The data doesn't look right. I assume that the analysis does require the stimuli presentation as a full circle, which means that the last 15 TR blank was accounted as the stimuli presentation time. If I am correct, is there simple way to take care of it in mkanalysis-sess? Second, the ring and wedge were presented in different frequency. It seems that the anslysis-sess does not take this into account in the current configration. Is there a way to specify this? Thanks very much for the help. Xiaomin
