 #### prepare the data for modeling   
 	First it will generate the points file for each complex in general, refined, core set. (The density of points can be specificed, low resolution OctSurf can use low density points to accelerate the process, here for depth=6 model, we use density 3. Can be specified in .sh file)   
 	Then the points and labels will be transformed into tfrecords file.
