I want to look at the beta values for all my conditions, voxel-by-voxel (in a specific ROI).  I have 180 conditions, and am not looking at a specific contrast. <br><div class="gmail_quote"><div><div class="h5"><div class="gmail_quote">

<br>When I open the beta.nii file produced by selxavg3-sess, and look at configure functional overlay, there are 215 &quot;timepoints&quot; listed (and 0 &quot;conditions). It appears that the beta values for the 180 conditions appear first, and there are 35 other regressors tacked on the end. When I open the h.nii file, there are 180 &quot;conditions&quot; and no timepoints. <br>




<br>However, when I read these into matlab using MRIread (to get the voxel-by-voxel values), there are 362 timepoints for h.nii and 216 timepoints for beta.nii. <br><br>Can someone point me to the specific documentation about the beta.nii and h.nii file, so I can know what these extra regressors are? Or alternatively, point me to a different file for extracting voxel-by-voxel beta values?<br>




<br>Thanks,<br><br>Emily Ward<font color="#888888"><br><br>
