Spatio-temporal dynamics of the proton motive force on single bacteria - dataset

Data set used in our manuscript "Spatio-temporal dynamics of the proton motive force on single bacteria" [Biorxiv].

To produce fig1 and fig2, unzip file in bash:

$ 7z e data_fig1_fig2.7z

Open fig1 data in python:

> b = pickle.load(open('fig1.p', 'rb'))

> b
