I’m trying to use filters.stats to output a summary of classes in a point cloud and the number of points per class as suggested on <a href="https://github.com/PDAL/PDAL/issues/955" target="_blank" class="">https://github.com/PDAL/PDA<wbr class="">L/issues/955</a>. But I’m not sure how to access the output of filters.stats. I tried to set up a pipeline as in the example, but the header in the output las doesn’t seem to include the new aggregate stats. If I change the output to text or STDOUT I only get the points back and furthermore it has all dimensions, not just those specified by the filters.stats dimensions field. What am I missing?
