ExploDiv dataset - temperature 200x8
Gerben Roelandt Stouten <G.R.Stouten@tudelft.nl>

This archive contains the raw cycle data of eight bioreactors (R1-R8) exposed to the feast-famine regime for over 200 cycles. 
The per second data of each cycle of 12 hours is stored in an HDF5 (Hierarchical Data Format: https://www.hdfgroup.org/HDF5/) 
file archive in the following file path structure: R1\R1 2015-06-29 11h00.h5.db. 
File names signify operational reactor, date and starttime of the cycle. 

NOTE: Each reactor folder contains a ‘bad’ folder with cycles that contain incomplete cycle data

python3.6 example code:

        data = store.get('data')
print("Cycle data covers: {} until {}\n".format(data.index[0], data.index[-1]))

Measurements performed every second by a collection of measurement equipment.
pH, DO is measured through DASGIP PH8DO8 system
acid and base are measured through DASGIP MP8 system
balance is measured through a serial interface with a Satorius CP34001S balance
ingas and offgas are measured by the ThermoScientific PrimBT Benchtop MassSpectrometer

pH is a <float> representing the system acidity
DO is a <float> representing the dissolved oxygen tension with 100% referring to liquid in balance with air
acid and base are <floats> representing the accumulated revolutions of the pumphead (reset every cycle)
balance <float> represents the readout from the feed balance in grams

N2, O2, CO2, Ar are <floats> representing the outgoing gas composition in %
N2in O2in, CO2in and Arin IDEM but for gas in
RMS is a <float> representing an approximation by the MassSpec of the gasflow coming from the system
RMSin is a <float> which does NOT represent the gasflow coming in the reactors.

NOTES: 
* RMS measurements lack precision and accuracy and should only be used for heuristics detection of gas connected or not.
* Offgas data is (linearly) interpolated between measurements to yield a continuous availability of data points
