title: Perturbing Manually

# Environment

Use the `perturb_manually.py` to initiate the perturbation environment. It uses `initial.pyc` as the target pyc file. While it utilizes the `temp.py` in `test` folder as where you can manually perturb.

Usage:

python bin/perturb_manually.py

For each iteration, it generates two files:
1. `initial.png`: This will be the cfg of the target file
2. `temp.png`: This will be the cfg for the perturbed file

Setup the windows as follows for effective testing:


# Reading supporting Data:

Additionally the script loads the data from previous data and finds closest matching for remaining of the target binary.

It outputs the meta data in file `temp.log`.

It first contains the closest matching code (seed):

Example:

And then following it, it contains code for each offset in target binary as follows:
