 # Pairwise Compare
 This tool allows the user to compare groups of data specified in a tidy-wide pandas dataframe with ease.
 In this repo the capabilities of the PairwiseCompareManger are shown through examples using a dataset from the [nf1_schwann_cell_painting_data](https://github.com/WayScience/nf1_schwann_cell_painting_data).
 These examples can be found in the docs.
 Although, most of the development efforts can be found in the `src` folder.

 If you choose to interact with another component of the tool, then there will be less input validation safeguards available.

 2. Additional column values are not tracked aside from columns used to compare groups (_same_columns, _different_columns).
 3. Output and input python data structures are limited.
 4. All of the data, in the supplied pandas dataframe, is used to compute comparisons.
 
 ## Extensibility
 This tool compares features between any two groups of a tidy-wide pandas dataframe.
-To incorporate additional comparators for making comparisons, you must introduce the functionality as a class and inherit from the `Comparator` class (See `Comparator.py` for details).
