Hi Everyone,<br><br>      I&#39;m new to freesurfer so I apologize if my question has already been answered previously (I searched the list archive and the website and couldn&#39;t find an answer).  I would like to make functionally defined ROIs for each of my subjects based on a localizer I used.  I would like to select several ROIs from one contrast.  I have done that by simply drawing the ROI on the significant voxels using the &quot;select voxels tool&quot; and saving that out as a label.  This process is rather painstaking though, and I was wondering if there was an easier way to do this- perhaps by selecting an entire cluster of voxels at once and saving that out to a label?  If anyone has figured out a more efficient way to do this I would appreciate it.  Thanks!<br>
