<p>Dear colleagues,</p>
<p><br>
</p>
<p>I use 3D <span style="font-size:12pt">landmark-based </span><font size="3">geometric morphometrics for statistical analyses of </font>morphological<font size="3"> variation in vertebrate skulls. I would like to know how I could create a heat map of a skull
that will show the deviations from the mean shape for a given effect around each landmark. </font></p>
<p><font size="3">For instance, the patterns of shape changes associated with a given Principal Component that would be mapped on a 3D skull representing the average mean shape. In this case, the visualisations of these deviations will be restricted and associated only
with the local landmark coordinates as opposed to a full heat map that would cover the entire skull.</font></p>

</font></p>
<p><font size="3">In fact, the exact thing I would like to achieve had been done in Figure 4A of this publication:</font></p>
