Hi,<br><br>If you're feeding in lower level feats, then you'll want the cope#.feat directories and the program will find the necessary files within those directories.<br><br>Hope that helps,<br>Jeanette<br><br><div class="gmail_quote">On Sun, Jan 22, 2012 at 12:29 PM, Andres Roman <span dir="ltr"><[log in to unmask]></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi FSL crew,<br> <br> I am running an analysis with multiple runs. In the feat manual it says :<br> <br> (To) combine across sessions to create COPEs for the subject means of each<br> subject, using a fixed-effects analysis. In the stats GUI, we select Fixed<br> effects. Then we setup the second-level analysis with 5 EVs, where each EV<br> picks out the 3 sessions that correspond to a particular subject.<br> <br> I did this and obtained good results which I can see on the browser report<br> that fsl gives you.<br> <br> Following this I did the between group comparison im interested in doing:<br> <br> Now we want the mean group effect, across subjects, achieved with a<br> third-level ME analysis. Select Inputs are lower-level FEAT directories and<br> select the 5 relevant directories created at second-level, named something<br> like subject_N.gfeat/cope1.feat.<br> <br> My question is what are the inputs I require for this comparisons? Is it the<br> <br> *.gfeat/cope1/stats/cope1.nii.<wbr>gz files I am interested in? Or is it the<br> *.gfeat/cope1/stats/zstat1.<wbr>nii.gz? It isnt very clear by the feat manual.<br> <br> Thank you very much for your help.<br> <br> Best wishes<br> <span class="HOEnZb"><font color="#888888"><br> --<br> Andres<br> </font></span></blockquote></div><br>
