 Convert unstructured Tecplot data to VTK. Note that if using voxel type data in VTK, the
-connectivity sequence is different from Tecplot. Note that the 3D connectivity sequence in
-Tecplot is the same with the `hexahedron` type in VTK, but different with the `voxel` type.
+connectivity sequence is different from Tecplot: the 3D connectivity sequence in Tecplot is
+the same as the `hexahedron` type in VTK, but different with the `voxel` type.
 The 2D connectivity sequence is the same as the `quad` type, but different with the `pixel`
 type. For example, in 3D the index conversion is:
