Hi<br><br>Does anyone know what this error message means?<br><br><br>SPM8: spm_spm (v2975)                              16:34:54 - 16/07/2009<br>========================================================================<br>Initialising parameters                 :                        ...done<br>
Output images                           :                ...initialisingFailed  &#39;Model estimation&#39;<br>Index exceeds matrix dimensions.<br><br>I have changed the design matrix manually in Matlab and removed the mask, but I don&#39;t think that is the issue.<br>
<br>Thanks<br><br>Joe<br>
