This [script](https://osf.io/mgnzc) checks that rates for valid reactions in a Webnucleo network file lie within an appropriate range for a set of temperatures.
To use, first download the file by typing
**curl -o check_rates.py -J -L https://osf.io/mgnzc/download**
Use the script on a Webnucleo network XML file (in this example, called *net.xml*). This will be an output from a Webnucleo network calculation, but, to obtain an [example](https://osf.io/kjnct/), type
**curl -o net.xml -J -L https://osf.io/kyhbs/download**
Then print forward or reverse rates less than the default low value 0 or greater than the default high value 1e20 for 20 logarithmically spaced temperatures between t9 = 0.01 and 10:
**python check_rates.py net.xml**
Change the printout by changing script options. To view those options, type
**python check_rates.py -h**
For example, to check only the forward rates for 5 logarithmically spaced temperatures between t9=5 and t9=10, type
**python check_rates.py net.xml --t9_low 5 --t9_pts 5 --forward_only True**
