Project description
cmerg
Python parser for CarMaker ERG files with Pandas dataframe export.
Use and Examples
Moslty these are notes for myself but hopefully someone else finds them useful.
Installation
This package is published on PyPI under the name cmerg.
Windows
> python -m pip install -U pip
> python -m pip install cmerg
Linux
$ python3 -m pip install -U pip
$ python3 -m pip install cmerg
Examples
Import the package folder.
import cmerg
Create ERG file object. (Using example file from repo)
log1 = cmerg.ERG('test-data/Test-Dataset-1_175937.erg')
List of the signals in the file.
log1.signals
Save the vehicle speed signal to a variable.
speed = log1.get('Vhcl.v')
Plot signal.
speed.plot()
Add signal to dataframe.
# New easy call to return a pandas dataframe.
df = log1.to_pd()
# Simple example of adding ERG data to pandas.
# TODO: Make 'toPd()' call
import cmerg
import pandas as pd
import numpy as np
log1 = cmerg.ERG('data-file.erg')
speed = log1.get('Vhcl.v')
t = np.array(speed.timestamps)
spd = np.array(speed.samples)
df = pd.DataFrame({'time':t, 'speed':spd})
