Hi, what happened to the script 02_plotting_two_features.py?
it disappeared from the repository and running it now causes an error

$ python 02_plotting_two_features.py 
Traceback (most recent call last):
  File "02_plotting_two_features.py", line 18, in <module>
    wot.io.add_row_metadata_to_dataset(ds, days_path=days_file)
TypeError: add_row_metadata_to_dataset() got an unexpected keyword argument 'days_path'

EDIT
the same error apears when running the script 03_plotting_cell_sets.py

EDIT2
I tried to change the days_path parameters to days.
It just gave me the next error

Traceback (most recent call last):
  File "03_plotting_cell_sets.py", line 33, in <module>
    cell_sets = wot.get_cells_in_gene_sets(gene_sets, ds,
AttributeError: module 'wot' has no attribute 'get_cells_in_gene_sets'
