JPKay

JPKay (pun intended) aims to provide tools to handle JPK force-files. It provides direct access to jpk-force files without the need to export them first. Data is loaded into a DataFrame and already converted to their respective SI units.

Currently under development, only CellHesion200 files are supported and analysis and plot tools are coming soon (®).

Usage

>>> jpk_file = r'path/to/jpk-force/file'
>>> sample = CellHesion(force_file=jpk_file)
>>> sample.data.head()

Plotting

>>> import matplotlib.pyplot as plt
>>> x = sample.data.retract.height * 10**6
>>> y = sample.data.retract.force * 10**12
>>> plt.plot(x, y)
>>> plt.xlabel("height [µm]"); plt.ylabel("force [pN]")
