CLI Bugs

[faberno]

Hey,
first of all thanks for this great library, it's a big help.
I wanted to report some bugs I encountered when using the CLI to reconstruct a mesh.

• The tessellation-level option is called tessellation-ratio in the code. This fails when arguments.tessellation_ratio is called
  

  VessMorphoVis/vmv/options/vessmorphovis_options.py

  Line 171 in 9044638

  self.mesh.tessellation_ratio = float(arguments.tessellation_ratio)

  
  Quickfixing this by changing the line to arguments.tessellation_level allows the program to continue, but setting the tessellation to another value than 1.0 will cause a TypeError: Converting py args to operator properties: : keyword "apply_as" unrecognized in the mesh builder.

• vmv.file does not have a function read_morphology_from_file
  

  VessMorphoVis/vmv/interface/cli/mesh_reconstruction.py

  Line 298 in 9044638

  loading_flag, cli_morphology = vmv.file.read_morphology_from_file(options=cli_options)

• only cli_options.mesh.export_obj is used to determine if vmv.file.export_mesh_object should be called, this ignores for example export-vascular-mesh-stl
  

  VessMorphoVis/vmv/interface/cli/mesh_reconstruction.py

  Line 112 in 9044638

  if cli_options.mesh.export_obj:

• vmv.file.export_mesh_object gets wrong arguments
  

  VessMorphoVis/vmv/interface/cli/mesh_reconstruction.py

  Lines 113 to 116 in 9044638

  	vmv.file.export_mesh_object(
  	mesh_object, cli_options.io.meshes_directory, cli_morphology.name,
  	cli_options.mesh.export_obj, cli_options.mesh.export_ply, cli_options.mesh.export_stl,
  	cli_options.mesh.export_blend)

• Even when mesh_objects from vmv.scene.get_list_of_meshes_in_scene() is just one mesh, it's still a list object
  

  VessMorphoVis/vmv/interface/cli/mesh_reconstruction.py

  Lines 100 to 109 in 9044638

  	mesh_objects = vmv.scene.get_list_of_meshes_in_scene()
  	if len(mesh_objects) == 0:
  	return
  	elif len(mesh_objects) == 1:
  	mesh_object = mesh_objects
  	else:
  	mesh_object = vmv.mesh.join_mesh_objects(mesh_objects, cli_morphology.name)

  
  I just fixed it by setting mesh_object = mesh_objects[0] when len(mesh_objects) == 1

When these points were fixed, everything worked as expected.
If you have any questions I can provide more accurate descriptions.
