Error: no color array found in the processed 3D data..

I want to generate SHOT feature on .ply files, and got an error.
Is color array necessary?

Hi @curehabit . I guess you may be using ColorSHOT instead of SHOT, i.e. you are not disabling color description setting the "-f" command line parameter when running the main file. Can you check?

Thank you! It works.
And I found another problem. When I set "-b 11", the shape of the result is k*388 rather than k*352. When I set "-b 0" , the shape is k*36. Is the result of this code expand traditional method (352 dimensions) with extra 36 dimensions, and save it in result[:, 0:36]?
