### Install Python Comtrade

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Install the module using pip. Alternatively, copy the comtrade.py file directly.

```bash
pip install comtrade
```

--------------------------------

### Load and Plot CFG/DAT Files

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Load COMTRADE data from separate CFG and DAT files and plot analog channels using matplotlib. Ensure matplotlib is installed for plotting.

```python
import matplotlib.pyplot as plt
import comtrade

rec = comtrade.load("sample_files/sample_ascii.cfg", "sample_files/sample_ascii.dat")
print("Trigger time = {}s".format(rec.trigger_time))

plt.figure()
plt.plot(rec.time, rec.analog[0])
plt.plot(rec.time, rec.analog[1])
plt.legend([rec.analog_channel_ids[0], rec.analog_channel_ids[1]])
plt.show()
```

--------------------------------

### Load COMTRADE Data as Pandas DataFrame

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Load COMTRADE data directly into a pandas DataFrame using load_as_dataframe or convert an existing Comtrade object to a DataFrame using to_dataframe(). Requires pandas to be installed.

```python
import comtrade
df = comtrade.load_as_dataframe("sample_files/sample_ascii.cfg")
print(df.head())

# Or, alternatively
rec = comtrade.load("sample_files/sample_ascii.cfg")
df = rec.to_dataframe()
print(df.head())
```

--------------------------------

### Run Unit Tests for COMTRADE Module

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Execute the module's unit tests using Python's unittest framework. This command should be run from a clone of the GitHub repository.

```shell
python3 -m unittest ./tests/tests.py
```

--------------------------------

### Load and Plot CFF Files

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Load COMTRADE data from a single CFF file (2013 revision) and plot analog channels using matplotlib. This method is specific to the 2013 revision.

```python
import matplotlib.pyplot as plt
import comtrade

rec = comtrade.load("sample_files/sample_ascii.cff")
print("Trigger time = {}s".format(rec.trigger_time))

plt.figure()
plt.plot(rec.time, rec.analog[0])
plt.plot(rec.time, rec.analog[1])
plt.legend([rec.analog_channel_ids[0], rec.analog_channel_ids[1]])
plt.show()
```

--------------------------------

### Initialize Comtrade with Numpy Arrays

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Enforce the use of numpy.array for data structures in the Comtrade object constructor. This can improve performance for data computations after loading.

```python
obj = Comtrade(use_numpy_arrays=True)
```

--------------------------------

### Load COMTRADE File with Specific Encoding

Source: https://github.com/dparrini/python-comtrade/blob/master/README.md

Load a COMTRADE file specifying a custom encoding. This is useful when dealing with files that do not use the default UTF-8 encoding.

```python
import comtrade
comtrade.load("sample_files/sample_ascii.cff", encoding="iso-8859-1")
```
