Extracting the knobs of a sequence

[sterbini]

Hi,

I would also add

def knobs_df(my_df):
    '''
    Extract the knob list of a pandas DF (it assumes that DF has a column called "knobs")
    and contanting lists
    
    Args:
        my_df: a pandas DF (it assumes that DF has a column called "knobs").
    Returns:
        A data frame of knobs.
    '''
    import itertools
    import numpy as np
    aux= list(my_df['knobs'].values)
    aux= list(np.unique(list(itertools.chain.from_iterable(aux))))
    my_dict={}
    for i in aux:
        my_dict[i]={}
        filter_df=knob_df(i, my_df)
        my_dict[i]['multeplicity']=len(filter_df)
        my_dict[i]['dependences']=list(filter_df.index)
    return pd.DataFrame(my_dict).transpose().sort_values('multeplicity', ascending=False)

to extract and sort "by-use" the knobs of a sequence or of the global space of MAD-X.
Cheers,
