def add_coords_to_experimental_metadata():

    """
    Script used to add the coords to the Experimental_metadata.yaml file.
    In order to work: 

    - The Experimental_metadata.yaml file needs to have the processing hybridization 
    and the coords at point 0 initialized: ex:  

    TilesPositions:  
    Hybridization1:  
        0:  

    - The coords file extracted from the Nikon microscope need to be in a text file
    ex. Hyb1_Coords.txt. The Coords tag is necessary and Hyb is the hybridization_key

    - The input parameters are passed via argparse

    Parameters:
    -----------
    hybridization_number: string
        Hybridization number (ex. 3) describing the hybridization to process.
    
    path: string 
        Exact path to the folder containing the text file with the coordinates.
    
    hybridization_key: string 
        Possible values 'Hyb' or 'Strip'. To add coordinates for stripping if necessary.
