Hi Folks, <br><br>We used to use tkmedit to add control points and recently started using freeview. <br>I have a few basic questions about saving controls points created with freeview.<br><br>1. I noticed that in tkmedit edit controls points were saved as &quot;control.dat&quot; in the &quot;subject_dir&quot;/tmp (e.g. bert/tmp).<br>

When I use freeview I assume I should also save the control points in the same location ? <br><br>2. If so, is there a way to configure freeview so that it saves it to &quot;subject_dir&quot;/tmp ?<br>(currently the default location where freeview saves the control points in the current  subject directory.)<br>

<br>3. Also I believe tkmedit saved the control points as &quot;control.dat&quot; but for freeview one has to specify the name manually. <br>Is there a command line  argument to set the name of the file as &quot;control.dat&quot; by default ?<br>

<br>Thanks<br>Mehul<br><br><br><br>
