Output

The output of MODE-Analysis is printed to the screen by default, as we saw, unless you redirect it to an output file using the -out command line option. View the output of the last MODE-Analysis job we ran by opening the $MET_TUTORIAL_DATA/output/mode_analysis/summary_job.out file with the text editor of your choice. For each of the four columns of data selected, the summary information consists of the following:

• Number of values being summarized.
• Minimum, maximum, mean, and standard deviation of the values.
• The 10th, 25th, 50th (median), 75th, and 90th percentiles of the values.
• The sum of the values, which is only really applicable to columns like AREA.

Close this file, and open up the $MET_TUTORIAL_DATA/output/mode_analysis/summary_job.dump file with the text editor of your choice. Look through the OBJECT_ID column (17th column) and verify that this file only contains pairs of simple objects of the form FNNN_ONNN. (To view the entire header, you can look back at the output files in your $MET_TUTORIAL_DATA/output/mode directory.) It is always a good idea to use the -dump_row command line option to verify that the MODE-Analysis job is performed over exactly the subset of MODE data that you intended.
