Hello, slicer community,  
I am using the surface registration module to align the two models and make quantitative measurement of the difference by model to model distance,then show the color map by shape population viewer.  
I wonder if it is possible to export error data so that I can analyze the distribution of errors, as shown in the picture below.

Thank you! Kind regards
