Output

By default, TC-Stat writes its job output to the screen but can easily be redirected to a file using the -out option. The -out option is specific to each job. When run on the command line, TC-Stat executes a single job. Therefore using the -out option once is sufficient. When run with a configuration file, the -out option should be specified once for each job defined in the jobs array.

The MET tarball also includes an Rscript which automates calls to TC-Stat and the generation of graphics. The scripts/Rscripts/plot_tcmpr.R Rscript performs two main steps: call TC-Stat to filter track data and create plots of the filtered track data. If Rscript or the R boot package are not available on your system, you may skip this step.

Plotting TCMPR lines

The plot_tcmpr.R Rscript requires that the MET_BUILD_BASE environment variable be set to the top-level MET source code directory and that TC-Stat be found in your path. Run the following commands based on whether you are using C-Shell or the Bourne Shell:

• Determine your shell:

• For C-Shell:

• For Bourne Shell:

Listed below are several examples of running this Rscript. The output printed to the screen lists the name of the output files. You may display them using a web browser, the display command, or any other graphics program.

• Run the Rscript with no arguments to see the usage:

• Specify an input file and output directory:

• By default, the script creates boxplots of event equalized track errors (TK_ERR). Display the output image:

• Turn off event equalization, plot only 3 models (OFCL, OCD5, and HWRF), and create several plot types for track and intensity errors:

The -no_ee option disables event equalization. The -filter options are passed directly to the TC-Stat filtering job. The -dep options specifies the column(s) of data to be plotted. The -plot specifies the desired plot types. Display the output images.

• Plot HWRF track errors broken down by storm intensity level:

The -series option overrides the default plotting by the AMODEL column. Use -title to override the default plot title. Display the output image:

These examples are meant as a brief introduction to this plotting script. We encourage you to run it many more times and try plotting different columns of data or pass different filtering options.
