Dear all,<br><br>I am trying to calculate the distance from a reference vertex to all other vertices in a surface mesh (or ideally to a subset of vertices), moving along the actual surface (e.g. smoothwm).  <br><br>I am able to loop through the pairs of vertices in which I&#39;m interested, using mris_pmake in each loop, but this is quite time consuming.  I have tried using &#39;--mpmProg autodijk&#39; as described in the mris_pmake help file, but have been unsuccessful at getting this command to work.  <br>
<br>The current code I am using for each pair is:<br><br>mris_pmake --subject &lt;subject&gt; --surface0 smoothwm --curv0 sulc --curv1 sulc --mpmOverlay euclidean --mpmProg pathFind --mpmArgs startVertex:###,endVertex:###<br>
<br>Any suggestions to cut down my processing time, while still calculating along the surface, would be greatly appreciated.<br><br>Andrew<br>
