Hi Bruce, thanks for the first response. I tried to find some information on the webpage about xform, but failed. So what is xform standing for and where/how can I check it? As in the later processing stages I want to do localization and DCM-Modeling with my data, I guess the correct talairach coords are kind of important for later comparisons. Thanks again, Maria
