Auto Classification not working

I have two .laz files loaded that I downloaded from the NOAA: Data Access Viewer website. When I try to classify ground (or anything else) nothing happens when I click the "classify features" button. I cannot find any reason why this should not be working. Anyone have this same problem? I'm using GM Pro v. 25.1

    You'll need to provide some more data for this, maybe a screenshot of your settings (the "automatic point cloud analysis" toolbar.

    I submitted a tech support request and received an answer. Turns out there is a known bug... It needs to be in a projected coordinate system to work.

    Have you tried exporting from GM as a .las whilst you have the projection you want in your main settings, then loading in the .las? I've found that when I spatially thin point clouds it won't let me run auto-classification on that layer, but if I export/import that layer then it works.

    Thanks NickV, it just needs to be in a projected coordinate system.

    Has the bug been resolved? I have a point cloud that we scanned using a terrestrial scanner. It is in state plane. For some reason when I go into the automatic point cloud analysis window, it will not let me select the check box of the point cloud I need to classify. If I go to Lidar Analysis> Automatic Classification> Ground then the Automatic Point Cloud Analysis window pops up with the correct point cloud checked but Classify Features is greyed out. Super quirky.

    Figure this one out... we simply closed and restarted the program and it works.
