WebAug 28, 2024 · The example script below assumes DIRSIG wrote to the file " tape5 ", it renames that file to " tmp.tp5 " and then launches MODTRAN6 supplying "tmp.tp5" as a command-line argument. Note that this rename approach was selected over the option of converting the input file to JSON in order to avoid the runtime associated with that … WebApr 22, 2024 · This guide outlines the command-line interface to the DIRSIG4 model. The goal of a robust set of command-line options is to better facilitate scripting and management of simulations. To address the limitations of the options in earlier releases, a new set of options were introduced with the DIRSIG 4.5.0 release.
