Hi All,<br><br>I&#39;d like to use mris_distance_map, but it looks like the usage/help info is missing or broken (At least in 4.4.0/4.5.0).  When I try it with just the command or -help, it looks like this:<br><br>mwaskom@ba2:~$ mris_distance_map --help<br>

usage: mris_distance_map [options] &lt;input surface file&gt; &lt;output scalar field (.mgz)&gt;<br><br>This program will compute a distance map of each point on the surface to a<br>reference point (vertex 0 by default)<br>

<br>valid options are:<br>mwaskom@ba2:~$<br><br>Can someone help me out with these mysterious options?  Also, how is it calculating distance?  Thanks!<br><br>Mike<br>
