Utility and test scripts¶

In the test/ and util/ subdirectories of the PISM directory the user will find some python scripts and one Matlab script, listed in Table 30. The python scripts are all documented at the Packages tab on the PISM Source Code Browser. The Python scripts all take option --help.

Table 30 Some scripts which help in using PISM¶
Script	Function
`test/vfnow.py`	Organizes the process of verifying PISM. Specifies standard refinement paths for each of the tests (section Verification).
`test/vnreport.py`	Automates the creation of convergence graphs like figures Fig. 35 – Fig. 39.
`util/pism_fill_missing`	Uses an approximation to Laplace’s equation $\nabla^{2} u = 0$ to smoothly replace missing values in a two-dimensional NetCDF variable. The “hole” is filled with an average of the boundary non-missing values. Depends on `netcdf4-python` and `scipy` Python packages.
`util/pism_flowline`	See section Using PISM for flow-line modeling.
`util/pism_check_stationarity`	Evaluate stationarity of a variable in a PISM `-ts_file` output.
`util/pism_nc2cdo`	Makes a netCDF file ready for Climate Data Operators (CDO).
`util/pism_nccmp`	A script comparing variables in a given pair of NetCDF files; used by PISM software tests.
`examples/preprocessing/flowlineslab.py`	See section Using PISM for flow-line modeling.
`examples/preprocessing/PISMNC.py`	Used by several Python example scripts to generate a PISM-compatible file with the right dimensions and time-axis.
