Working Directories

Typical working directory layout for a FRED simulation:

fred.inp file

An input file is always needed. The default name is fred.inp.

inp folder

An optional directory inp can contain auxiliary files (e.g. DICOM files, user-defined HU calibration curves, treatment plan files, etc.).

out folder

The out directory is populated by output files and results produced by FRED.

plugin folder

A plugin directory can contain user-written code in the form of a dynamically loaded plugin that expands the capability of FRED code.

All these locations can be redefined using command line options, e.g.

fred -f myInputFile
fred -i myInputDirectory
fred -o myOutputDirectory
fred -plugindir myPluginDirectory


The output directory is completely erased each time a simulation is run.
