Image file "fd_smooth01/directions.mif" does not contain fixel data (wrong dimensions)

I tried to run fixelcfestats commands from step 23 for performing statistical analysis:Fibre density and cross-section - Multi-tissue CSD — MRtrix 3.0 documentation, after running all the previous steps.
I get the following error:
[ERROR] Image file “fd_smooth01/directions.mif” does not contain fixel data (wrong dimensions)
