Contents:

There are two self-contained R files that fit the proposed respiration model to experimental data. The codes are well anottated and self-explanatory. They read raw and proceesed data from accompanying folders and produce tabulated outputs and figures. A figures folder contains all the figures that are included in the paper and generated by these codes.

Both R codes will load the required packages at the start of execution.

Data used for model testing were obtained by one the following:

1. Digitizing published figures

2. Supplemental materials published by other researchers.
