2. Filtering by slicing the index

Problem:

• Axes in Panel: major, minor
• Index in df: iter, id

Config.yaml refers to major, minor: now these should be:

• major -> 'iter'
• minor -> 'id'

Line 293:

filtered = d.iloc[(d.index.get_level_values('set').isin(param['set'])) & (d.index.get_level_values('run').isin(param['run'])) & (d.index.get_level_values('iter').isin(param['major'])) & (d.index.get_level_values('id').isin(param['minor']))][var_list].dropna().astype(float)
