Hi<br><br>If I have say 30 trials of my experiment, how do I put that into SPM. So far I&#39;ve been working with analysed data (i.e. summation of all trials).<br><br>At the moment I have each file as a 4D matrix with a time series of 60 scans. However when I put this into SPM i notice that the design matrix has 30 rows when it should have 60 (representing the 60 scans) or even 60*30 (representing the 30 repetitions of 60 scans.<br>
<br>Thanks<br><br>Joe<br>
